Sendmail not presenting AUTH option after EHLO
Hello folks,
I have a CentOS 6.4 installation running Sendmail, and after some serious hair tear stare and compare I'm a bit stumped. When I connect to the server either with telnet or SSL, sendmail is not presenting the AUTH capability after an EHLO. Everything looks like it should be working, but no amount of tweaking is getting the AUTH capability advertised (and it doesn't work if

submission configuration issues
Hello,
I'm having trouble configuring the submission proxy.
I have configured the submission service as follow:
submission_host = smtp.example.com
submission_relay_host = localhost
submission_relay_port = 8587
submission_relay_rawlog_dir = /var/log/dovecot/
submission_relay_trusted = yes
My main issue is that until I login, dovecot-submission won't connect to the backend and query the

Submission service and SMTP AUTH capability
Hi Everyone!
I've setup dovecot 2.3.2.1 on a Gentoo server. I want to configure the
submission service in order to replace the corresponding part in Postfix
(which is my SMTP server).
I configured submission it with just a few options different of the
default ones:
submission_client_workarounds = whitespace-before-path
submission_relay_host = 127.0.0.1
submission_relay_port = 10026

SMTP auth with Sendmail
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

dovecot-submission SMTP send error with Thunderbird (BODY=8BITMIME)
Hi,
With latest 2.3 -git (and 2.3.0 release), I'm running into this error
with Thunderbird:
"An error occurred while sending mail. The mail server responded: 5.5.4
Unsupported mail BODY type. Please verify that your email address is
correct in your account settings and try again."
This is fatal and means Thunderbird cannot use the submission service -

slowness in sendmail - 60 second timeout
I am sending an email from my machine devcentos5x64.
the transcript below (hangs for 60 seconds) at the line:
MAIL From:<root at devcentos5x64.msgnet.com> SIZE=56
AUTH=root at devcentos5x64.msgnet.com
The email succeeds - but I am trying to figure out the 60 second delay.
Neither email server is busy. Nothing is waiting.

No AUTH PLAIN with dovecot 2.0.19
Hi
I have installed the package dovecot-postfix on Ubuntu 12.04 LTS:
dovecot --version: 2.0.19
postconf -d | grep version: 2.9.6
and receiving email works very fine, but relaying email does not work.
I think the problem is that after STARTTLS the authentication is not
being executed

250-AUTH=PLAIN
which means using telnet returns

setting up postfix
This should be an easy one. I'm trying to get postfix going. I've
never done this before. I followed the directions at
http://wiki.centos.org/HowTos/postfix. I opened port 25:
iptables -I INPUT -p tcp -m tcp --dport 25 -j ACCEPT
Here's an attempt to send mail:

Help Getting Postfix relaying via Gmail
Hi,
I am trying to get a CentOS 6 system relaying mail via my G-Mail account.
I followed the instructions found at
https://www.zulius.com/how-to/set-up-postfix-with-a-remote-smtp-relay-host/but
there seems to be a problem with authentication. I have done some
research but still can't get this working. Any suggestions ? It seems the
user and password are correct.

problem with disable_plaintext_auth
Hi,
I am using dovecot with postfix for authentication.
Everything (TLS/SSL, authentication) is working fine, except that when
I set:
disable_plaintext_auth = yes
I still can authenticate with plain text on a no TLS/SSL session:
