hello

I lately get several times a day the Active Monitor message that the SMTP 
server isn't running and couldn't be restarted. 15min later the all-clear 
message drops in, everything ok. Thank you BO, Michael and all others for the 
automatic assistance!:-)

But I still wonder what's the cause of this... I browsed through the log files 
/var/log/maillog /var/log/messages /var/log/secure with no clues to anything 
suspicious (or I didn't know what to look for).

The GUI's Security > Failed Logins page mentioned several IPs and two users; I 
blocked IPs in the APF Firewall Blacklist and suspended the two users. That helped 
insofar that the SMTP stalls occurred now _only_ a couple of times a day instead 
of almost hourly...

Any hint what I could do else?

Thank you and best regards
