This is probably more of a Postfix issue than ISPConfig, but it is an ISPConfig setup that was working. Ubuntu 18.04.02 / ISPConfig 3.1.13p1 A user reported she can't sent emails anymore. I tested it with a simple mail command as root and it didn't work for me either. # cat /var/log/mail.log |grep jpcyrenne Feb 10 21:46:29 hote3 postfix/error[25547]: D0C12360661: to=<[email protected]>, relay=none, delay=0.13, delays=0.1/0/0/0.02, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused) Feb 10 21:49:48 hote3 postfix/smtp[25863]: C5BE9360681: to=<[email protected]>, relay=none, delay=0.11, delays=0.1/0.01/0/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10024: Connection refused) I double checked the /etc/postfix/master.cf configurations. https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/ I added the sending domain it he Email/Domain section of ISPConfig. There is no Email Mailbox. I restarted postfix and even restarted the server to be sure all services were restarted... no success (as root in shell). Thanks ahead for your help. JP
If you changed the configuration, that may be why e-mail is not working now. When you have a working system, and it suddenly stops working, do not change configuration. Search for the error and fix that error. Your ISPConfig version is not the latest, consider updating. For the e-mail problem, start with https://www.howtoforge.com/community/threads/please-read-before-posting.58408/ Then, are all services running now? Code: systemctl --state=failed
@Taleman, thank you for your response. I only added the domain because it wasn't working (trying stuff since it only had a website). Maybe it did the trick? This morning, when I check, I see my emails from last night have come in. About 40 minutes after I posted this thread? - I still updated the ISPConfig to 3.1.15p2 (good practice) - I rant the trouble shooting script (nice tool I'll keep in my arsenal - thanks again). Everything did look good in there. - # systemctl --state=failed 0 loaded units listed. Pass --all to see loaded but inactive units, too. To show all installed unit files use 'systemctl list-unit-files'. Thank you once again, JP
