using sendmail MSP to forward mail to a central server

I've configured postfix as an MTA on my network, but for all the other 
machines, I just want to forward all mail directly to the central server. 
This means I don't really want a local sendmail server on each box.

The questions I have are:

1. Is is OK to use FEATURE(`msp', `mailserver.my.domain') in submit.mc to 
send mail across the internal network, and should I do anything else in 
submit.mc to get sendmail to connect to my postfix server?
2. What's the recommended way of rewriting the To: address? It's useful to 
(somehow) preserve the original machine the mail was gerenated on. I've 
seen stuff about user+detail (e.g. root+server1@my.domain) - can I do this 
with aliases, and if so, how?
3. The From: address should be the FQDN of the originating machine. This 
seems to be OK, as this is the default behaviour.

unable to forward mail from 1 sendmail server to another sendmail server
Hi, i have a setup like this: box A ---> box B ---> sends to the world. sendmail, solaris 9. what is happening is as follows: Application on box A generates mail (for the users, who can be from anywhere) forwards it to box B which sends it out. The box A is forwarding mail to box B, only for the users of the domain, ie if there is a user is having a gmail id the mail is NOT forwarded from box A ----> box B. If i do a nslookup on gmail on box A it resolves properly.

how to force sendmail to forward mails to another mail server?
Hi all, Currently we have 2 machines for mail (a smtp server and a pop server) Currently, sendmail accepts and sends out mail for our domain. We'd like sendmail to just send out mails but when it receives mails, it should forward it to our pop server. should we use mailertable for this or some other method? thanks for any info ike lozada schrieb: > Hi all, > > Currently we have 2 machines for mail (a smtp server and a pop server) > Currently, sendmail accepts and sends out mail for our domain.

Just enter your domain in the mailertable, but on the receiving side there must be a mta, too, of course. So both servers should be running, e.g. sendmail. the pop server has to allow relaying of the smtp server, too. Keep your receiving server in brackets in the mailertable entry to prevent dns lookups, like so yourdomain.com smtp:[internalserver.internaldomain.com] Tim Tim Aden <corrodan@netcologne.de> wrote in message news:<c08rl4$3ft$1@newsreader2.netcologne.de>... > ike lozada schrieb: > > > Hi all, > > > > Currently we have 2 machines for mail (a smtp server and a pop server) > > Currently, sendmail accepts and sends out mail for our domain.

Questions on setting up Sendmail as a central mail server
Hello everyone. I spent the past few days famalirizing myself with sendmail. Building my ..cf file, customizing .mc, m4 usage etc. I am doing this on FreeBSD 4.9. I found out that what works best for me is to download the source (8.12.11) and compile it by hand. My question is this. I am going to put up Sendmail as our company mail server. It is most likely going to sit on the DMZ and as it stands right now, the only people who should be able to send mail out through this mail server are the users that are on my intranet. I did build sendmail with milter, saslv2, and starttls. I know SMTP-AUTH is a very handy way to ensure additional security for sendmail. With that in mind, I was hoping to get some additional recommendatinos to further ensure that my server is as secured and locked down as possible. For instance, I know there is the access file and access.db (which im still reading about in the Bat Book) which could further help in securing my mail server. I still have a lot to learn and much to go over in the bat book as it seems there are endless amount of options I can specify with sendmail. For now though, I was hoping I could get some additional feedback on my particular setup to make sure I am heading down the correct path. I appreciate everyones help. Jason ...

clarification needed on working of a mail server using sendmail
Greetings All, I have some confusion regarding working of a mail server . Please help me in clarifying this point. The scenario is like this. There is a mail server running in our organisation for sending mail ( sendmail ) . No POP and IMAP service are running on this mail server and we use to check our mails using webmail , a PHP based webmail program. I have configured EVOLUTION and in the sending mail option , I have used SMTP as the server type and in the server's ip address i have to the mail server. I have not configured the receive mail section as there is no POP and IMAP service running in our network. As far as my understanding goes , I should be able to send mail using evolution as it is configured for SMTP and the mail server is a working mail server . Now when I try to send mail , I receive the following error. "" Error while performing operation. MAIL FROM command failed: Access denied "" Please clarify me why I am getting this error and using the above configuration is it possible to send mail regards zaman ...

Sendmail must forward all local mails to corporate SMTP server!

mails sent by sendmail were treated as junk mail
Hi there, I am a newbie of sendmail and trying to configure it to work as my main mailserver which allow POP3 and SMTP connection from outside. My problem is that I cannot send out any mails which appears like sender: xxx@mydomain.com. If I send mail through terminal, my sent-out mail would looks like aaa@hostname.mydomain.com instead of aaa@mydomain.com. hostnam.mydomain.com is a qualified name of my linux box runing sendmail. Second, I configured a openwebmail on this linux box to allow users login from anywhere to manager their mails, and it works fine. However, all the out-going mails sent throug openwebmail are treated as junk mail by most mail server like hotmail and yahoo. It was complained as unknown sender(at this case, sender appears aaa@mydomain.com) Does anyone have any experience in such situation or have any ideas how to configure sendmail to solve my problems? My network setting is simply as router -> DMZ zone -> linux box which is runing sendmail. I have a domain, mydomain.com, which is parking at a domain hosting company where my zone file is actually located. I changed the MX record in the zone file so that it points to my static ip address(eg. 10.11.12.113). After some simple changes were done, I can receive any emails sent to my domain, like xxx@mydomain.com. Thanks for any ideas!

HTML mail using sendmail
I am trying to use sendmail to send an HTML email. Is there something special in the header to let the email client know that it is an html file? I am creating a flat file with all the required information but when I put in the body of the email (Html) it just sends the html commands and that is what is displayed in the email.

You are in the wrong newsgroup. You should learn about generating MIME compliant e-mail messages. Many languages like Perl or PHP have libraries that can do just that. It is also considered bad behaviour to send HTML only e-mails. Not all e-mail clients can read them. Always provide an alternative plain text message.

Securing a Sendmail mail server
This actually is more along the lines of ensuring that your server is not an open relay and to ensure that only my internal LAN and users authenticated via smtp-auth have the ability to send mail through my mail server. I've been pouring over the bat book and the new sendmail cookbook and feel like i've made good progress in figuring out how to secure my server. However, I wanted to post a few questions here to verify that I am understanding this correctly and when my server goes live, I am not an open relay. I know as of sendmail 8.9, it is a closed relay by default. Which is very nice. Ok, here is my initial setup. I have our company LAN which should be the only people who can send mail through the server. I also added smtp-auth for further security. What I have done is specify in my .mc file to use the acess_db. I then put in the first three octets of our subnet. I also have the option FEATURE(`use_cw_file') as well and created a local-host-names file located in /etc/mail. I then placed our company domain inside of that file. With that in mind, should that work to ensure my server is protected? Last thing I want is to put up this server incorrectly and then have serious problems. I should also note, that I do want to leave options open for scalability, as we are planning on expanding down the road. I appreciate the help.

Sending mail without sendmail or highly secure sendmail
Hello all, I am setting up a very secure Red Hat Enterprise Linux Advanced Server version 4 update 6 server. My sendmail version is 8.13.1. My mail server is a Windows 2003 Server with Exchange 2003 with its patches. They are both on the same subnet. DNS is on and it will resolve the mail server's name and IP. SSH, SCP, SFTP, and such tools are the only networkable protocols on. NFS if off, MOUNTD is off, PORTMAP is off, and such. Until just recently sendmail was off on the RHEL server as part of the hardening procedure. However part of the auditing requirements is for a mail message to go out to some admin if certain events occur such as "disk is full," "a panic occurred," "the system rebooted" etc. So I will perhaps cut sendmail on and mitigate the risk as best as possible. So, this sounds dumb, but can you send mail without sendmail. I think perhaps no, but I thought I'd ask anyway. Secondly does anyone have a harden .mc file from which they could share what they did? Of course you can fudge in phoney IP and names to protect your secured environment. Advice or insight do any of you have on securing sendmail is appreciated? I want to avoid such things as promiscuous relays, unqualified senders, etc etc. But if it must be ... it must be. :) Thanks George <george.e.sullivan@saic.com> wrote: > I am setting up a very secure Red Hat Enterprise Linux Advanced Server > version 4 update 6 server.

using sendmail to send outoign mail only
Hi guys. I've set up a linux server (only running squid). I want mail from the root account on that machine to be sent to my email address. like RAID error notifications and stuff like that. I'v elooked everywhere, and everything seems to be working OK, but I can't send outgoing mail to external email accounts i have. the mail always appears to come from root@host.mydomain.com and not from root@mydomain.com if i use a smarthost that i allow relaying through, the return address appears ok, but in the message headers i still see root@host.mydomain.com. when using FEATURE(`relay_based_on_MX') the mail is sent to the appropriate mx, but isn't relayed from there. some relays say "DSN: Data format error" some say "DSN: User unknown" and some say it's ok, but the mail never gets to me. I looked at the logs, and i think it's related to the from: header. the mx for the external domains i'm sending mail to don't accept mail from the non-existant domain host.mydomain.com, and rightfully so, as there's no such domain. any ideas? what am i doing wrong? I don't need to recieve incoming mail at all, only to allow mail sent using "mail someone@somedomain.com" to go to the right direction. I can't use my ISP, cause it requires me to log into my pop account before sending outgoing mail. thanks.
