TLS support on postfix
Hi List,
I have a postfix server based on CentOS 5 in which I have been trying to add TLS encryption support for SMTP.
From the localhost when I do an EHLO, following is the output
[root at xxxxxxx ~]# nc localhost 25
220 xxxxxxx.xxxx.xxx.xx ESMTP Postfix
EHLO localhost
250-xxxxxxx.xxxx.xxx.xx

Dovecot submission announces CHUNKING but backend Postfix does not support it
Hello,
I'm setting up Dovecot 2.3.2.1 as a submission proxy to a Postfix
backend server. Dovecot announces CHUNKING, but the Postfix backend does
not support (or announce) it.
HELO from Postfix:

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
in the logs, it doesn't even try to authenticate, the cyrus sasl rpm

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
250-AUTH=PLAIN
which means using telnet returns
telnet mx2.wyona.com 587

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

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:
20 mail2.cs.ait.ac.th ESMTP Postfix (2.6.2)

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 -

tls not working with postfix in chroot mode on centos4.0
hey friends,
I am trying to make postfix run with tls in chroot mode, but I am not
able to send the messages with tls on. I am using postfix 2.2.10 on
centos 4.0 and I had compiled the postfix from sources with tls &
cyrus-sasl support. I copied the certificates from /usr/share/ssl to
/etc/postfix.
Below are the errors I am getting:

submission configuration issues
service submission-login {
? inet_listener submissions {
? ? haproxy = no
? ? port = 465
? ? reuse_port = no
? ? ssl = yes
? }
}
Shouldn't the port be 587 here?
My config file looks like:
service submission-login {
? inet_listener submission {
??? #port = 587
? }
}
The # comment must also mean something..

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:

Postfix and Dovecot SASL
Hello all,
I am struggeling to get my Dovecot SASL to work within postfix. I have used
the configuration example listed on the main-site of dovecot and it
basically isn't giving me any success at all. I am probably missing
something easy, but after spending a few days testing and walking through
everything I could think about I thought figured it was better to ask :)
Hope someone can point me

Postfix, Dovecot SASL and Entourage smtps authentication fails.
Tere.
Recently just migrated from Sendmail 8.14.3 to Postfix 2.5.6 and
switched from Cyrus-sasl 2.1.22 to Dovecot 1.1.13 sasl, all are compiled
from source and I have used Dovecot for a long time, since alpha versions.
Everything worked well for Outlook Express, Outlook and Thunderbird
clients, but Microsoft Entourage 2004 or 2008 clients smtps fails -
