similar to: How to use different SASL mechanisms for ssl connections

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

Okay, I wasn't going to try and fix up the messed up mail server I was given; however, I decided that I might as well try. Situation: The system has a Postfix MTA and uses Dovecot for LDA and Cyrus-SASL for SASL. That works fine. I decided that I wanted to switch over to Dovecot for SASL. dovecot is presently using MySQL for its database. I make the (I thought) necessary changes in Postfix

Hello Folks, I've been the admin of a site that uses Postfix with Dovecot on RedHat since, oh, gosh, maybe 1996? It's been a long time. I've never built it from source, though, just used the rpms (and I wonder if maybe that's my problem now). It just works, is reliable, and lets me be a very-part-time administrator. Repeatedly over the last few years I've been asked to have

Hi I have configured one line in postfix main.cf (after configure each line I check /var/log/mail.err): smtpd_tls_dh1024_param_file = /etc/postfix/dh2048.pem After setup above line I have error in above log file (these 4 lines looped): Apr 25 14:08:09 serwer-1 dovecot: imap-login: Error: SSL: Stacked error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol Apr 25 14:08:09

Hi, I am trying to create an authenticated relay server using Postfix and Dovecot. However I am having two problems : (a) If I create a dovecot config entry as follows : unix_listener /var/spool/postfix-authrelay/private/dovecot-auth { group = postfix mode = 0666 user = postfix } Dovecot is unable to create the socket ? I thought surely if dovecot is started as root it should

Hello dovecot, I want to have all authorization in one place and don't use Cyrus-SASL. I cobfigure postfix 2.3.3 to use dovecot-SASL. I have next lines in main.cf: smtpd_sasl_security_options = noplaintext,noanonymous smtpd_sasl_tls_security_options = noanonymous But PLAIN and LOGIN are advertised by postfix :( Is it bug of postfix or dovecot-auth? I don't want to disable

I turned of ssl_cipher_list in dovecot.conf file (so it's default) but test still gives errors: Apr 27 08:55:06 serwer-1 dovecot: pop3-login: Error: SSL: Stacked error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol Apr 27 08:55:06 serwer-1 dovecot: pop3-login: Error: SSL: Stacked error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol Apr 27 08:55:07

Thank You for answers. But: 1. How should be properly configured ssl_cipher_list? 2. Ok, removed !TLSv1 !TLSv1.1. 3. Strange thing with ssl_protocols and ssl_cipher_list, because on older server on Ubuntu 14.04 LTS, dovecot 2.2.9 and postfix 2.11.0 these two lines looks exactly this same and no errors in mail.err file and mailes works without any problem. 4. No, currently I don't use LMTP.

Cipher list which You post provide better compatibility or security than those which I currently have? On older software version these cipher list works well and not generate any errors when I run Internal PCI scan test from https://cloud.tenable.com for another server. But for new server with newer software during test I got errors in mail.err. 2017-04-27 10:00 GMT+02:00 Aki Tuomi <aki.tuomi

Hi, I'm trying to configure a new server with dovecot 2.0 and postfix 2.6.6. My previous servers have all been dovecot 1.x. Trying to port over my previous configurations has been a real headache.
