similar to: Confusion over sendmail and smtp auth on a 6.2

I'm reading a lot on how to setup my smtp auth on a new Centos 6.2 server. I want to use sendmail and have this running on a Centos 3 machine now, so it's not new stuff to me. Unfortunately, the more I read, the more confusion I seem to have. Firstly, how to generate my certificates. A good recommendation or howto would be in order. I think most of the confusion here comes from the

Amazing what you find when you sit down and read CAREFULLY. The answer to generating a sendmail certificate was in the sendmail.mc file. Same place as it has been for quite some time. Sorry for the bother. steve

Hello! After moving from Centos 5.6 to Centos 6, I figured that Sendmail minor version was updated from 8.13.x to 8.14 and Dovecto from 1.2 to 2.0.x In previous configuration SMTP auth worked fine (no SASAUTHD neccessary) for virtual users table. Dovecot was authenticating virtual users virtual checking dovecot.passwd file. I'm not sure how Sendmail was processing SMTP AUTH for virtual users

Try this article, "Outbound authentication for Sendmail." http://www.databook.bz/?page_id=3097 I wrote this after setting it up on my own CentOS server.

Hi list I searched the net, but could not find something related. Is it possible to export the client socket to sendmail for smtp auth? What would be the sendmail.mc configuration for this? #client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. #path =

A while back I struggled to get Domainkeys and DKIM to work properly on my little home server. While I'm sure they weren't necessary in a strict sense, it not only enabled me to learn about the technology but allowed for more of a verification of the email coming from my server. And so this week I figured: "Hey, this has been working without a problem for a while; it must be time to

Which backend does it use? For debugging

Dear All, I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm

Hi All, I have set up three servers in a development environment. Via CR they're updated to Centos 6.2 It appears that these servers have postfix installed on them by default, which unfortunately I'm not very well acquainted with. All I want is a quick and dirty way to enable these hosts to send email through my own SMTP host. My (sendmail) SMTP host uses SMTP AUTH on a non-standard

Hello all, I've been googling my brains out since yesterday looking for up-to-date information on this matter, and have found information that is anywhere from 15 to 5 years old. I'd really like some information that much more up to date on the subject. Specifically configuring Sendmail SMTP authentication (_no smart host stuff_). I've got Sendmail 8.14 installed on a CentOS 7.3

Dear CentOS Community Is totally clear there's no support sendmail platform today, but I need to stop SMTP brute-force attack on sendmail.
