hi, Im not sure why but i noted that all of a sudden two days ago i stopped getting emails from my server. I found that this Code: systemctl list-units --failed UNIT LOAD ACTIVE SUB DESCRIPTION ● [email protected] loaded failed failed Postfix Mail Transport Agent (inst LOAD = Reflects whether the unit definition was properly loaded. ACTIVE = The high-level unit activation state, i.e. generalization of SUB. SUB = The low-level unit activation state, values depend on unit type. I did not change anything myself but maybe a change due to an update or a hack? I checked the /var/log/mail.err for the last entry: Code: Sep 18 19:48:13 server1 dovecot: auth-worker(5322): Error: mysql(localhost): Connect failed to database (dbispconfig): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) - waiting for 1 seconds before retry Sep 18 19:48:14 server1 dovecot: auth-worker(5322): Error: mysql(localhost): Connect failed to database (dbispconfig): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) - waiting for 5 seconds before retry Sep 18 19:48:19 server1 dovecot: auth-worker(5322): Error: mysql(localhost): Connect failed to database (dbispconfig): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) - waiting for 25 seconds before retry /var/log/syslog looks ok from what i see, but im not sure about this: Code: Sep 19 16:32:50 server1 snmpd[2148]: error on subcontainer 'ia_addr' insert (-1) please advise
No it is running, all websites are working, including searching for contents, its only mail that is not working for some reason? postfix.service is working but not [email protected]
Not sure what [email protected] is as postfix is usually postfix.service and only that service should run.

Not sure wht the script cant find my IP address with ifconfig, maybe because i also have a slave DNS? 2. My SSH port is not 22 so dont worry about that, its works as it should
Postfix seems to be running fine and postfix is listening to the correct ports. Please login to webmail and send an email to the same address that you are logged in to webmail. Then please post the lines that got added for this action in /var/log/mail.log file.
Yes I managed to get the postfix working again, but I think the reason for it failing was because it was overload because of a hack, im getting many failed to send emails, which i did not send, from the undelivered mail header shows: Code: X-Mailer: Infraware POLARIS Mobile Mailer v2.5 but i do not know what this is, so i need to look into my web file-system and see if a hack-script has been added.
