Hi! It seems there are problem with POP3 connection when TLS enabled. Previously it worked fine, but for now it doesn't... Plain & SSL POP3 works. Plain, TLS & SSL IMAP works too.

Hi, first of all, many thanks for a great piece of software. Today I updated one of our 2 IMAP/POP3 proxies from version 2.2.15.17-1 to 2.2.23.1-1 (both are enterprise editions).

Hello everyone, I've been asked by a colleague to have a look at some extremely weird dovecot SSL issue they are seeing on one of the student mailservers. They are running dovecot 1.1.6 (yes, I know, a bit old ...) on SLES 10.2 x86_64 with imap(+starttls), imaps, pop3(+starttls) and pop3s enabled. Every couple of weeks the pop3s and pop3+starttls part bail out out. Clients can't connect,

What kind of test are you running?

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 using openldap 2.0.23 and samba 2.2.4 on a Redhat 7.2 Linux distrib. I've compiled with ldap support dans It works fine in clear mode. I've configured unix auth. in order to use ldap on TLS mode, and it works also. When I try to use TLS more (or SSL on 636), it doesn't work. LDAP doesn't seem to have an error (see logs below), but samba tells "Failed to issue the

Hi, can anyone tell me where these "unknown users" come from. As far as I see the fact, dovecot is asked by postfix to look for the password of the recipient-user (why ever). +++ Jan 7 19:43:09 f42252se postfix/smtpd[14625]: initializing the server-side TLS engine Jan 7 19:43:09 f42252se postfix/tlsmgr[14627]: open smtpd TLS cache btree:/var/lib/postfix/smtpd_scache Jan 7 19:43:09

There's submission on port 587 or submissions (formerly called smtps) on port 465

Recently thunderbird and Dovecot IMAPS cannot agree on SSL however Evolution, on the exact same system, is working fine with the same accounts. Tried recreating the Dovecot cert and also the thunderbird accounts from scratch. The OpenSSL raw client works fine as well. Would someone also confirm the openssl commands to create a selfsigned cert for dovecot imaps. They cert created does work

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.
