I have both postfix and dovecot running. Command: sudo postfix status
postfix/postfix-script: the Postfix mail system is running: PID: 38284 Command: sudo systemctl status dovecot.service Active: active (running) since Mon 2021-12-06 12:48:45 UTC; 2h 29min ago I've checked all 3 mysql connections using postmap. They connected with the correct response for sizzelicks.com, smok...@sizzelicks.com <mailto:smok...@sizzelicks.com> and spa...@sizzelicks.com <mailto:spa...@sizzelicks.com> (alias) like they did before. I have verified that ufw allows the appropriate ports (see below). I stopped postfix and dovecot. I cleared the log, then started postfix and dovecot (successfully this time). I attempted to send an email to smok...@sizzelicks.com <mailto:smok...@sizzelicks.com> . It bounced. I attempted to connect via Thunderbird to the mailbox of smok...@sizzelicks.com <mailto:smok...@sizzelicks.com> . The mail server set (smtp & imap) was mail.sizzelicks.com. The error was connection timed out. In the log I see a few attempts to connect from spammers. I do not see my laptop IP or anything at all about what I did. You see I can send this email from my laptop just fine, yes? Also I used telnet from my laptop to sizzelicks.com on port 25 and connected with no problem. It returned aecperformance.com which is what I have myhostname set as in main.cf The certificate set in main.cf is the certificate chain for my websites (all working fine under ssl). /etc/letsencrypt/live/aecperformance.com/fullchain.pem /etc/letsencrypt/live/aecperformance.com/privkey.pem mail.log Dec 6 15:20:02 softlinksys postfix/postfix-script[38115]: warning: symlink leaves directory: /etc/postfix/./makedefs.out Dec 6 15:20:02 softlinksys postfix/postfix-script[38282]: starting the Postfix mail system Dec 6 15:20:02 softlinksys postfix/master[38284]: daemon started -- version 3.4.13, configuration /etc/postfix Dec 6 15:20:13 softlinksys dovecot: master: Dovecot v2.3.7.2 (3c910f64b) starting up for imap, pop3, lmtp (core dumps disabled) Dec 6 15:20:30 softlinksys dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<s.pet...@softlinksys.com>, method=PLAIN, rip=79.106.224.142, lip=194.163.45.150, TLS, session=<bEr1y3vSR9hPauCO> Dec 6 15:20:40 softlinksys postfix/smtpd[38325]: warning: hostname ip-201-148-246-68.sulig.net.br does not resolve to address 201.148.246.68 Dec 6 15:20:40 softlinksys postfix/smtpd[38325]: connect from unknown[201.148.246.68] Dec 6 15:20:41 softlinksys postfix/smtpd[38325]: lost connection after EHLO from unknown[201.148.246.68] Dec 6 15:20:41 softlinksys postfix/smtpd[38325]: disconnect from unknown[201.148.246.68] ehlo=1 commands=1 Dec 6 15:24:01 softlinksys postfix/anvil[38328]: statistics: max connection rate 1/60s for (smtp:201.148.246.68) at Dec 6 15:20:40 Dec 6 15:24:01 softlinksys postfix/anvil[38328]: statistics: max connection count 1 for (smtp:201.148.246.68) at Dec 6 15:20:40 Dec 6 15:24:01 softlinksys postfix/anvil[38328]: statistics: max cache size 1 at Dec 6 15:20:40 Dec 6 15:24:02 softlinksys dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<d.sut...@softlinksys.com>, method=PLAIN, rip=103.5.75.215, lip=194.163.45.150, TLS, session=<0/Gc2HvSPetnBUvX> sudo ufw status Status: active To Action From -- ------ ---- 22 ALLOW Anywhere 21 ALLOW Anywhere 20 ALLOW Anywhere 80 ALLOW Anywhere 443 ALLOW Anywhere 3306 ALLOW 67.8.3.170 25 ALLOW Anywhere 465 ALLOW Anywhere 587 ALLOW Anywhere 110 ALLOW Anywhere 995 ALLOW Anywhere 993 ALLOW Anywhere 22 (v6) ALLOW Anywhere (v6) 21 (v6) ALLOW Anywhere (v6) 20 (v6) ALLOW Anywhere (v6) 80 (v6) ALLOW Anywhere (v6) 443 (v6) ALLOW Anywhere (v6) 25 (v6) ALLOW Anywhere (v6) 465 (v6) ALLOW Anywhere (v6) 587 (v6) ALLOW Anywhere (v6) 110 (v6) ALLOW Anywhere (v6) 995 (v6) ALLOW Anywhere (v6) 993 (v6) ALLOW Anywhere (v6) Kristy Atkins ViviData SaaS
