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

While certainly Centos 6.2 specific, I found the following How-tos very helpful in setting up a similar Sendmail/Dovecot configuration on Centos. http://www.falkotimme.com/howtos/sendmail_smtp_auth_tls/index.php http://www.brennan.id.au/12-Sendmail_Server.html Hope it helps.

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

I've been trying to get smtp auth set up for days. All my sendmail and sasl2 stuff seems to be proper, but the user can't use the system on port 587, which is where I require authorization. Now I see where messages are in my maillog of the type: auth: pam_unix(dovecot:auth) : authentication failure ........ Why is dovecot involved in my smtp processes and how do I fix this. I've

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 =

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

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

Which backend does it use? For debugging

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

I'm having problems with what I think is PAM. Seems that ever since Centos 5, proftpd has had problems using pam, and with Centos 6.2 64 bit, I had to quit using it altogether with proftpd. Now I'm trying to set up SMTP AUTH using PAM as the pwcheck parm to saslauthd, and I can't setup new email accounts on my port submission (587) to work at all. We use this port of sendmail so

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

Dear CentOS Community Is totally clear there's no support sendmail platform today, but I need to stop SMTP brute-force attack on sendmail. My server is attacked today, my maillog look like : 4624 at myserver.com>, proto=ESMTP, daemon=MTA, relay=myserver.com [127.0.0.1] Jun 14 19:07:01 at6412 sendmail[24627]: q5EN71jC024627: from=<>, size=3958, class=0, nrcpts=1,

I use Google Apps for my domain, hosted on a CentOS server. How could I setup my sendmail.mc to route Sendmail mails through the Gmail SMTP? Any help would be greatly appreciated.
