Hi guys, i am using ubuntu 20.04 with ispconfig 3 according to: https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/ I setup a complete fresh server today because i had email problems with other servers before, so i moved from one server to server 2 and to server 3 without solving the problem, so i decided to install a complete fresh server to check what is going on. (email [email protected]) the last problems i had here: https://www.howtoforge.com/community/threads/mail-problem.88377/ When i setup a new email i get the following error in the logs: (after that i setup a new password for the email but however its the same problem) maybe because i moved the domains today to the new server? Code: Feb 13 15:07:08 server6 dovecot: auth-worker(193487): Warning: sqlpool(mysql): Query failed, retrying: Connection was killed Feb 13 15:07:08 server6 dovecot: auth-worker(193487): Error: sql([email protected],31.14.63.61,<20LA0ObXnLAfDj89>): Password query failed: Connection was killed Feb 13 15:07:10 server6 dovecot: imap-login: Disconnected (auth service reported temporary failure): user=<[email protected]>, method=PLAIN, rip=31.14.63.61, lip=144.91.80.244, TLS, session=<20LA0ObXnLAfDj89> Feb 13 15:07:10 server6 dovecot: auth-worker(193487): Warning: sqlpool(mysql): Query failed, retrying: Connection was killed Feb 13 15:07:11 server6 dovecot: auth-worker(193487): Error: sql(hewlett,5.34.205.118): Password query failed: Connection was killed Feb 13 15:07:12 server6 postfix/smtpd[351521]: warning: unknown[5.34.205.118]: SASL LOGIN authentication failed: UGFzc3dvcmQ6 Feb 13 15:07:12 server6 postfix/smtpd[351521]: disconnect from unknown[5.34.205.118] ehlo=1 auth=0/1 rset=1 quit=1 commands=3/4 Feb 13 15:07:14 server6 dovecot: auth-worker(193487): Warning: sqlpool(mysql): Query failed, retrying: Connection was killed Feb 13 15:07:14 server6 dovecot: auth-worker(193487): Error: sql([email protected],31.14.63.61,<AJzm0ObXnrAfDj89>): Password query failed: Connection was killed Feb 13 15:07:16 server6 dovecot: imap-login: Disconnected (auth service reported temporary failure): user=<[email protected]>, method=PLAIN, rip=31.14.63.61, lip=144.91.80.244, TLS, session=<AJzm0ObXnrAfDj89> Feb 13 15:07:16 server6 postfix/smtpd[351378]: connect from unknown[5.34.205.118] Feb 13 15:07:18 server6 postfix/anvil[345636]: statistics: max connection rate 7/60s for (smtp:5.34.205.118) at Feb 13 15:01:42 Feb 13 15:07:18 server6 postfix/anvil[345636]: statistics: max connection count 3 for (smtp:5.34.205.118) at Feb 13 15:00:43 Feb 13 15:07:18 server6 postfix/anvil[345636]: statistics: max cache size 2 at Feb 13 14:57:36 with webmail i cannot login as well. Do you have any idea what i can do to make the email work? thanks for your big help
Seems as if MariaDB is not working correctly, so connections from dovecot fail. Check the /var/log/syslog file for errors and also the log files form mariadb. Does the server has enough RAM?
hi thanks for your answer. update : login works with webmail and i can connect via IMAP as well. Code: Feb 13 15:32:54 server6 dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=547822, secured, session=<o27vLOfXToN/AAAB> Feb 13 15:32:54 server6 dovecot: imap([email protected])<547822><o27vLOfXToN/AAAB>: Logged out in=50 out=540 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 i was confused with a password so now the connection is working, but the email does not arrive when i want to send an email i get from the email programm: error tls handshake The server is a VPS with 4 GB RAM if i look for mysql error in syslog i get nothing: Code: root@server6:~# tail -f /var/log/syslog | grep mysql in roundcube the emails do not arrive but i can login
moreover i can send an email with roundcube and the email arrives as well only receiving is not possible
Update: another email is now working on the server so the server is working well. I assume, that the email which does not work is because the DNS are with cloudflare so maybe it take some time until it will work
Login with roundcube to a local account of your server, then send an email to the same account that you logged into RoundCube. If it arrives in the account after a few seconds, then your mail server itself is working properly.
Hi thanks for care about my problems. When i login in Roundcube and send an email to myself so it arrives well without any problems. thanks a lot as always for your big help and thats on a sunday
Hi there again, to receive emails is no problem, but i can not send emails Code: Feb 14 16:42:01 server6 postfix/submission/smtpd[760006]: connect from unknown[31.14.62.136] Feb 14 16:42:01 server6 postfix/submission/smtpd[760006]: lost connection after CONNECT from unknown[31.14.62.136] Feb 14 16:42:01 server6 postfix/submission/smtpd[760006]: disconnect from unknown[31.14.62.136] commands=0/0 the email program says: Code: error performing tls handshake , an unexpected tls package was received how can i find the problem with that? thanks again
