similar to: Dovecot is not reading connections from iOS devices correctly. Any ideas?

From the dovecot logs. dovecot-info.log May 11 09:27:45 imap-login: Info: Aborted login (no auth attempts in 0 secs): user=<>, rip=192.168.0.1, lip=192.168.0.15, session=<pXcBJ8oVbgDAqAAB> dovecot-debug.log May 11 09:27:45 auth: Debug: auth client connected (pid=17388) When I try to connect using either the iOS Mail app, or Outlook mail app, nothing happens at al with ssl, and

Uh, "pop3s" != "imap", and IMAP/STARTTLS is not the same as IMAP/SSL (or whatever the hell the terminology is nowadays). If you're testing IMAP, try one or the other or both depending of how many flavours

can?t access mail after some upgrades. Everything else seems to be working - but dovecot seems to have caught a problem.

Hello list we encounter a weird SSL issue with one of our dovecot (2.2.24 on Centos6) which we can only explain if our assumtion is correct Symptoms are that imaps connections (on port 993) suddenly get veeeery slow. Up to 180s for one connection with openssl s_client The thing we do not understand is that in the same time imap connections with starttls are just 1s. We can see that entropy on the

Hello all; Is anyone knows if it's possible to have a dual certificate setup on dovecot like in postfix or apache ? i tried to add several crts in local name section : local_name imap.server.tdl { ssl_cert = <server_rsa_crt.pem ssl_key = <server_rsa_key.pem ssl_cert = <server_ecdsa_crt.pem ssl_key = <server_ecdsa_key.pem } but it seems that dovecot takes the last one (ecdsa)

Andrew, Thanks for the pointers about looking into the ldap client libs. I think I've found a situation where tls connections to the AD server on port 389 have trouble. I've added the CA cert to ldap.conf, and to the ca_root_nss file on this system. First what works: 1. ldapsearch commands with -Z to force use of tls (configured in /usr/local/etc/ldap.conf) 2. ssl connections with

Hi we are using dovecot on secure port when i try to command openssl s_client -connect mail.mydomain:pop3s it works perfect.

Hello list, I'm trying to get pidgeonhole/managesieve running, and I'm stuck connecting clients to the server (Dovecot 2.2.33.2-1ubuntu4.1 on an Ubnutu 18.04 machine).

Hi, I have a small question with sendmail and tls verification. The tls verify fails on our internal/external sendmail servers. For example: STARTTLS=server, relay=mx1.imt-systems.com [89.146.219.60], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 STARTTLS=server, relay=acsinet12.imt-systems.com [89.146.219.42], version=TLSv1/SSLv3, verify=FAIL,
