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.

routing sendmail through another sendmail server
Hi all; I have a SendMail issue. Please help, as I am a newbie with Sendmail: We have a server (weasel.foo.org) that has a port opened in our firewall to an Exchange server in a DMZ. I can send mail from this server to our Exchange server just fine. However, we have other servers that generate e-mail from various scripts, processes, applications, etc. that we would like to receive as well. The idea is to use weasel as a relay to forward the mail through the firewall, instead of setting up a bunch of firewall rules to allow mail from numerous servers. On one such server (hobbes), I have my s...

Can sendmail execute a vrfy against another sendmail server?
We're trying to do some initial screening for another server. Is there a way in the rulesets while processing an incoming message to grab the recipient address, do a quick vrfy against the destination mail server, stash the result in a local map then either reject the message or accept it for queuing?

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 w...

problem with sendmail, not sending mails to some mail servers like yahoo except gmail
hi this is sasidhar, we have CentOS5 with default sendmail configuration. Initially it is sending mails to gmail, yahoo etc. last few days it is not sending mails to yahoo.

Sendmail must forward all local mails to corporate SMTP server!
Hi, I am setting up Bugzilla on linux system and as such it will use the linux mail command to forward its emails. So I need to get a sendmail configuration which will send *every* mail sent using unix mail to the corporation SMTP server (smtp.mycorp.com) That server requires login and password plus SSL. I am thinking that this is a common config, but I am not seeing any help as I search various places.

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...

Not to my knowledge. Can you run a packet trace (WireShark, tcpdump, etc.) of both sessions (the one to A _and_ the one to B), and then compare them? I suspect that B is somehow prompting Exchange to send ...

Sendmail Server-Server TLS
Hi! I have set up a new sendmail installation on a server running slackware to recieve email for a domain. Is there some way to force/encourage servers sending mail to addresses at this server to use TLS? i.e. user@domain1 --> domain1 smtp server --> domain 2 smtp server Try and make the link between the two smtp servers secure?

Now that you have enabled TLS, all email that you send/receive to/from domains which also have TLS enabled will be encrypted automatically. If you have LogLevel>=3D9, look for log entries containing "STARTTLS=3Dserver" (receiving) and STARTTLS=3Dclient (sending) to see which servers this is happening with.

Sendmail virtual hosting, default mail server
Hi, googl'd quite a lot but couldn't find my answer. Can someone help ? We host several domains, on a single server. The server has different IP addresses, corresponding to the SMTP and POP servers for the domains. Domains are virtual in the sense that we don't use the the virtusertable, but the vdeliver utility of linuxconf : users don't have an account on our system. Everything works fine, e-mails are delivered and sent OK. Our question is the following : Is it possible to have sendmail send the mails from the "domain mail server" instead as from the local loop ? ...

Making sendmail work with my ISPs mail server
I am running sendmail on Solaris 9. Normally I use Mozilla to do most of my email, with mail.charter.net set as the outgoing server (SMTP), but would like on occassion to use mailx instead. The problem is I can not get sendmail configured so it will send mail via mail.charter.net. I have tried 2 or 3 different sets of sendmail.cf changes based on what I have found using Google, but none of them work. Local mail is fine, but mail addressed to jack_morrison@charter.net gets sent but never received.

To reduce spam, you should also put a list of all users into the access table. That way, mail for invalid users will never even be forwarded in the first place.

Best way to send mail from sendmail server?
Hey all; I've got a sendmail (8.13.4) box primarily relaying from the outside to a number of inside locations. Problem is, this box also sends mail out itself, mostly reporting and such. Now any mail it generates is coming from "user@localhost" which resolves (naturally) to 127.0.0.1. I can add localhost to the access DB and it works fine, but I'm wondering if this is really the ideal way of doing things. Is there a way I can rewrite the sender domain from localhost to domain.com, or even host.domain.com?

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.

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 ...
