Greetings, I'm refining a CentOs configuration installation, now just over one month old running on a colocated production server. Previously, we ran a version of Fedora for over seven years. Specifically, I'm reviewing our sendmail configuration, both with respect to authentication and port usage. Previously, we had the following line in the sendmail.mc line:

I am looking for a way for sendmail to ALLOW auth by IP and not user name (its a closed network) or even SKIP invalid auth ? Is that even possible ? Jerry

...sendmail to ALLOW auth by IP and not user name > (its a closed network) or even SKIP invalid auth ? > Is that even possible ? It is possible to configure Sendmail to relay based on client connection. The doc will tell you how. https://www.sendmail.org/~ca/email/doc8.12/cf/m4/anti_spam.html#access_db If your Sendmail setup demands AUTH, then it will not skip in case of false credentials. Whatever backend you configure cyrus-sasl to use for validating the SMTP AUTH credentials, it is possible to use other values than a user name. > Jerry Alexander

I think my sendmail is not correctly set. It says the default is to disallow relaying. I am running centos 4.8 and I think sendmail is relaying for anything. Based on this: http://www.sendmail.org/~ca/email/chk-89f.html#RELAYING I added|: FEATURE(relay_hosts_only) to my sendmail.mc file and restarted sendmail. I am still seeing connects that get relayed and are not in my /etc/mail/access

Maybe someone can help me sort this out. I want to block outbound mail from my network based upon the recipient address. Internal servers should still be allowed to send emails, but not to a few specific addresses. I've tried creating some rules in /etc/mail/access but to no avail. Is it possible to do this?

I was getting MANY emails from XXX.hinet.net - kind of filled my mqueue directory. I stopped sendmail. removed all the files in mqueue, added to sendmail access a REJECT for hinet.net This certainly seems to help - but is that the correct way to take care of this sort of thing? Thanks, Jerry

Hi all, I've been trying to hit on the right configuration combo to allow relaying from specific users and/or domains to an internal box running Sendmail. Reading the docs at http://www.sendmail.org/m4/anti_spam.html#relay and http://www.sendmail.org/m4/anti_spam.html#access_db_fine I would appear that I should be able to all per-address relaying in /etc/mail/access by enabling FEATURE(`relay_mail_from')dnl in sendmail.mc and restarting Sendmail. Then adding test at testdomain.com to /etc/access as: From:test at testdomain.com RELAY Should allow relaying F...

Hi - OK not really an Asterisk question but it is affecting one of my favorite features - emailing voice mail! I've posted on some Linux forums and sendmail.org but no response so I'm hoping someone will take pity on me ;-) My ISP requires SMTP authorization and I'm having a heck of a time getting it to work. I've included the following below: Asterisk 1.4.21 CentOS 5 Sendmail

I know this is a "generic" question, but fully CentOS related. I attempted to set up i386 v.4.1 on my primary computer at the co-located site, and thought I had everything squared away till I discovered the machine was refusing mail connections. AFIK, I had no firewall or other objects blocking port 25. It has been my experience that with most arch's and versions where sendmail is
