Sendmail authentificates, client cann still send mails with fake "Mail From:" tag

hello,

i've just finished my first AUTH sendmail configuration, client cann
authentificate himself via LOGIN/PLAIN with TLS. I've noticed though
that sendmail doesn't pose any restraints regarding the mail from: tag.
lets say my domain is test.de, my loginname ist alex
now i cand send mails from arbitrary name@ test.de...actually from
arbitrary name @ arbitrary domain :)

Am i missing something here ?

what i would like is: user authentificates -> he is allowed to send
mail only  with the prior stipulated address (his address)
Thanks!

Regards,
Alex

Assuming you have

user:alex                alex@example.com

echo -e ".D{auth_authen}alex\ncheck_rewrite_sender alex@example.com" |
sendmail -bt

Would be allowed.

echo -e ".D{auth_authen}alex\ncheck_rewrite_sender alex@example.net" |
sendmail -bt

Would not be allowed

At this point I cant quite figure out what you are telling me.

If you want, you can take this off-public and I can poke around the
system with you to take a look.

first of all, a great compliment to jmaimon@ttec.com, Thanks for the
time!

Well if someone is interested why it didn't work out straightaway, the
reason is that i use SOLARIS 10 and the rules
->  http://www.jmaimon.com/sendmail/patches/rewrite_sender.tar.gz
need some minor changes

--> replace "storage" with "macro" in the rules

and btw makemap has to be made in such a way:
--> makemap -de btree /etc/mail/fromaddrs < /etc/mail/fromaddrs


That's all, it works great now! :)

Best regards,
Alex

"Microsoft ESMTP MAIL Service" misleading the Sendmail by BODY=7BIT in "mail from"
Hello. I ran into a situation where the Sendmail deceived by the Microsoft ESMTP MAIL Service. MS ESMTP Service send to Sendmail MAIL FROM:<system@gosuslugi.ru> SIZE=12345 AUTH=<> BODY=7BIT but message is not 7BIT. It contain MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="--2f2da5fd4e757bb09dce3cc4fd3fda88" Content-Transfer-Encoding: 7bit in header, but ----59b9b79d39a2fcdcd7600d2d20592b5a Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: 8bit in some parts and real text in utf8. Sendmail loses one bit. :-( A second big problem - a huge E-Mail providers such as GMail or Mail.ru ignore the "BODY=7BIT" and messages accepted propertly. I find it difficult to prove that the problem should be resolved by the message sender or the postmaster of "Microsoft ESMTP MAIL Service". Any idea ? -- Regards, Sergey.

Difference between "mail" and "sendmail"
What is the basic difference between "mail" ad "sendmail"? I tried both in the following ways mail [emailid] <filename1 sendmail -t -i <filename2 for mail, filename1 contains the body of the mail for sendmail,filename2 contains all the headers including to,from,subject,contenttype etc. When I was testing both the above to send mails to yahoo account, I could find that "mail" is able to send 30-40 mails per second, but for sendmail, it's taking 30-40 seconds for 1 email to be sent. When I did strace in both cases I found that after sending data to DNS server,"poll" times out after 5 seconds in the case of "sendmail". It will try again and it will times out again. After 3-4 timing outs, the "poll" will return within 1 second and mail will be sent. When "mail" is used, "poll" will return quickly even though the connection is going to same DNS server and also the mail is sent to the same yahoo id. I need to use "sendmail" as it's supporting multipart mails. I would really appreciate your help, Thank you, Benny In short, 'mail' is a client program wheres 'sendmail' is a server program. They are also called MUA and MTA (Mail User Agent vs. Mail Transfer Agent). Sendmail implements the SMTP listening on port 25, and it is pretty much the same program in all Unixes. Mail may be rewritten by the vendor (Solaris, AIX, etc.). As you noticed, 'mail...

mail::sendmail (SOMETIMES) get "bad file descriptor" error when mail not local
I have a leased Linux box that I installed mail::Sendmail on using CPAN I'm using a perl script to send mail. I have a domain on that server and I get my personel email at that address. The script works fine when I am using my own email address as the recipient, but when I try to send to any other domain I get, for example, "sendmail failure sending to somebody@otherdomain.org Bad file descriptor" I don't have this problem with by Linux box at home and I thought I configured it the same way. (I just let CPAN do it's thing) I noticed that there is a soft link to qmail on the remote server, but it was my understanding that mail::Sendmail is independant of other mail programs. Is there some configuration file I can change to solve this problem? Anyone have any ideas?

iBook and Mail, no "send mail" sound
A friend of mine has a white iBook (G3, I think, running Panther). She has always liked the "whoosh" sound of mail being sent from Apple Mail, but she said it disappeared after some geek relatives were visiting for the holidays (maybe just a coincidence). The file that causes the sound, "Mail Sent.aiff," accessible by viewing Mail's package contents, is definitely in her Mail app, andn other sounds are working fine in all applications. Another issue that might be related: She has never done any maintenance (with Disk Utility or something like MacJanitor), and never shuts down or restarts--she just closes the lid when she's not using it, keeps Mail and Safari open, etc. I heard that the automatic UNIX maintenance doesn't wake up a laptop to do its thing.

Sendmail sends mail with "no valid sender in any header line"
Why is sendmail sending mail with "no valid sender"?? I just moved to a new server, using Sendmail 8.13.8. I can receive emails fine and some hosts accept emails from my domain. However, in my sendmail logs, I see many of the the following error messages: Feb 21 20:01:06 xxxx sm-mta[51025]: STARTTLS=client, relay=hosthidden.com., version=TLSv1/SSLv3, verify=FAIL, cipher=AES256-SHA, bits=256/256 Feb 21 20:01:12 xxxx sm-mta[51025]: l1M4158b051022: to=<user@hosthidden.com>, ctladdr=<rakey@host2hidden.com> (1003/1004), delay=00:00:07, xdelay=00:00:06, mailer=esmtp, pri=31147, relay=hosthidden.com. [209.123.15.18], dsn=5.0.0, stat=Service unavailable My colleague says his ISP told him the service unavailable message is due to the email being rejected because: "rejected after DATA: there is no valid sender in any header line" So, why is sendmail sending mail with "no valid sender"?

Question on "Mail Queue" and "sending"
Hi, As you know, when you send an email, the email is in the queue, then the status become.. "sending" We are using our SMTP email server from our Internet provider. We have sometimes ( rarely ) all our emails blocked into the queue. ( "Deferred with.. smtp.example.com" It sounds that this is not the email server from our internet provider, but ONE mail seems to block everything.. but the problem is : which one ???? * Restarting the server doesn't help * Even the reception is blocked ( I can see with my fresh email Backup that news email are in the backup server.. If I delete everything and restart Sendmail everything is back OK ! but this solution is a bit extrem.... - Is there a way to tell the server, that if you have a problem with ONE email... leave it in the queue and send the others ?

If, as you say, you're using your ISP's server, all that should happen at your end is that you send an email and out it goes. What happens to it once it hits the server is not only completely out of your control, you're not even notified unless there's a long delay -- generally speaking, you're not told about delays lasting under 24 hours or so.

Problem using the "nail" or the "mail" command to receive E-mail. HELP!!!
Using the "nail" or the "mail" command to send and receive E-mail. Examine this line: ls -a ~ | nail -a .mailrc -A autosend -s "Dis be a tess" dock@technologist.com I have been using this line at a command prompt to send an E-mail with the subject line "Dis be a tess" using my E-mail account back to my E- mail account. What this particular line does is: list the directory using the "ls" command. It then pipes the output from the "ls" command to a "nail" command. The parameters in the "nail" command a...

E-mail Aliases in "Mail"
Suppose that my on-line store, mystore.com, sell hats and gloves. The company that hosts my site has assigned the e-mail address (and user name) mystore@mystore.com to this account. But they will forward mail addressed to anynamewhatsoever@mystore.com; in other words, they allow me to use an unlimited number of e-mail aliases. That way, a person who wants to enquire about a hat can e-mail hats@mystore.com and a person who is interested in gloves can e-mail gloves@mystore.com. Filters in "Mail" will sort the messages into the appropriate mailboxes for my convenience. The problem is t...

"Unreal" mail users in Sendmail+OpenLDAP
Hi everyone, I have FreeBSD 5.4, sendmail+tls+sasl2+ldap-8.14.0, openldap-2.3.34. Everything works fine BUT... PROBLEM. --- I don't want to create mail users in the system. I'd like to have all of them in one LDAP database. --- How messages will go i.e. to one /var/spool/mail or should I create real directories to every each of mail users? --- What schema should I use? --- I'd like to see an example of "fake" mail users LDIF file. --- Is there any specific configuration of Sendmail and OpenLDAP except standard ones in this special case?

sendmail/cyrus accepts mails for "unknown users"
Hi, the info-cyrus maillingliste told me to place my question here: I'm runnung sendmail 8.12.3 (Debian woody standard package) with cyrusv2mailer (cyrusv2.m4,v 1.1 2002/06/01) and cyrus 2.1.17 (backport from http://people.debian.org/~hmh/). Today I had a heavy spam attack caused by the fact, that sendmail accepts mails for non existing users (all addresses are defined in aliases or virtusertable). Emails those unknown accounts on local domains (local-host-names) will be accepted and than(!) bounced. Is there a way to stop/reject these mails at "rcpt to: user unknown"-point?...

Sendmail keeps rejecting my mails "Domain not found"...
Hello everyone, Ok, my problem is as follows: I keep getting this error message when trying to send mail ************* The original message was received at Wed, 20 Dec 2006 15:16:08 -0600 from localhost.localdomain [127.0.0.1] ----- The following addresses had permanent fatal errors ----- <xxx@sunset.com.mx> (reason: 550 <root@vader.sunset.com.mx>: Sender address rejected: Domain not found) ----- Transcript of session follows ----- .... while talking to akenaton.sunset.com.mx.: >>> DATA <<< 550 <root@vader.sunset.com.mx>: Sender address rejected: Domain not found 550 5.1.1 <xxx@sunset.com.mx>... User unknown <<< 554 Error: no valid recipients ************* vader.sunset.com.mx does not have a DNS record, as it is an internal machine, with no outside access, so akenaton, wich is the company's public mail server, rejects mails from vader. Ok, so after doing some reading, i edited akenaton /etc/mail/local-host-names file, included vader.sunset.com.mx, and restarted sendmail. I have also edited the domain masquerade option at vader, so that it masquerades hosts vader.sunset.com.mx to just sunset.com.mx, wich passes through the mailserver just fine. However, I keep getting rejected with the same error message. Is there something left to do that I'm missing here?

Apple Mail rule to prevent "New Mail" sound from playing?
I have an Apple Mail rule that identifies certain emails as possible Spam. The rule transfers the email to another mailbox and marks it as read. However, when such an email arrives, the "new mail" sound is played. Is there something that I can add to this rule that would prevent that from happening? Of course, if there is other new mail that shows up at the same time, I'd like the "new mail" sound to be played.

Apple Mail; mail doesn't get to server to be "saved"
I'm still one of those increasingly few AOL users (got kids). Have had the account since '95. Anyway, when I got cable access at work, I decided to use my Mac Mini in the office to not only access my work email, but also the AOL account which I use at home for personal stuff. Running Tiger 10.4.7 and Apple Mail on both systems (G4 at home). Things worked fine for months; I simply configured the Mail application to access my office mail server and also my AOL account, which is IMAP. I only use AOL at home. When I use Mail at work, I still get all of my normal AOL mail. I think that wha...

Bug 6.1.2 ? " Leave Mail on Server" Second Mail Account
I upgraded two of my computers with Eudora 6.1.2 today. I upgraded Eudora clients with the same two email ISP accounts configures on both computers. The primary Dominant account works fine. I can read and pop from the first email accounts withouth any problems it leaves the mail on servers and deletes it after 5 days on the ISP Server. Both Clients can pop the emails independently With the second Account, once I check email , and I run a check mail again it deletes the mail from the ISP server. I can no longer pop from a second email client. The setting on properties is to leave the mail on the server. If anyone can help, I would really appreciate it. - Frank Frank Domanico <fd@diamondbullet.com> wrote: > I upgraded two of my computers with Eudora 6.1.2 today.
