I'm on: Debian GNU/Linux 9.9 (stretch) ISPConfig 3.1.14p2 I just configured my first mailbox... but can't send emails out. This is the line in /etc/mail.log that says it all: Code: postfix/smtp: 6AE6540516: to=<[email protected]>, relay=none, delay=0.14, delays=0.13/0/0/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10026: Connection refused) By now I googled so much I found out 10026 is an amavis port and it is supposed to be up and running. But it's not reported in netstat as open (neither is 10024) : Code: # netstat -tanp|grep 100 tcp 0 0 127.0.0.1:10023 0.0.0.0:* LISTEN 847/postgrey --pidf tcp 0 0 127.0.0.1:10025 0.0.0.0:* LISTEN 6667/master tcp 0 0 127.0.0.1:10027 0.0.0.0:* LISTEN 6667/master tcp6 0 0 :::3306 :::* LISTEN 1004/mysqld And I get this "(exited)" is not looking too good, upon doing "/etc/init.d/amavis status" : Code: ● amavis.service - LSB: Starts amavisd-new mailfilter Loaded: loaded (/etc/init.d/amavis; generated; vendor preset: enabled) Active: active (exited) since Tue 2019-07-30 14:52:10 CEST; 26min ago Docs: man:systemd-sysv-generator(8) Process: 8382 ExecStop=/etc/init.d/amavis stop (code=exited, status=0/SUCCESS) Process: 8388 ExecStart=/etc/init.d/amavis start (code=exited, status=0/SUCCESS) Tasks: 0 (limit: 4915) CGroup: /system.slice/amavis.service Jul 30 14:52:10 <mydomain> systemd: Stopped LSB: Starts amavisd-new mailfilter. Jul 30 14:52:10 <mydomain> systemd: Starting LSB: Starts amavisd-new mailfilter... Jul 30 14:52:10 <mydomain> systemd: Started LSB: Starts amavisd-new mailfilter. Also I get no logs from amavis. Apparently "something" makes amavis exiting... so I thought, let's make it log. I changed the log level into 5 (in /etc/amavis/conf.d/50-user) . But it doesn't create a /var/log/amavis.log (as configured). Nor does it append its loglines onto mail.log (as some sources say on the net)... I must have made a mistake somewhere, somehow. How to fix this without messing up my install (I do have a couple of non-emailing sites running ok). Thanks ia for your help.
