Proxmox Mail Gateway Log Error

Good afternoon,

My Proxmox Mail Gateway is popping up a log message:

postfix/postscreen[21493]: CONNECT from []:43262 to []:25

postfix/postscreen[21504]: fatal: error [-30986] seeking /var/lib/postfix/postscreen_cache.db: Success

postfix/master[1771]: warning: process /usr/lib/postfix/sbin/postscreen pid 21504 exit status 1

If anyone can help me with this mistake, I am grateful. Thanks in advance.

That's odd - the message would indicate one of 3 things to me:
* the db-file /var/lib/postfix/postscreen_cache.db got corrupted somehow - you could try removing it and restarting postfix
* something installed some incompatible berkeley-db headers and utils on your system and postfix mistakenly uses them (rather unlikely) did you install any other packages on that system? - What's the output of
ldd /usr/lib/postfix/sbin/postscreen
* something else is wrong with the system - do you have any errors in the journal or dmesg?

I hope this helps!
as said - most likely the file just got corrupted - try removing it and restart postfix afterwards
Good Morning!
Thank you!
I was able to solve the problem with the indicated solution
