Panic/Fatal error in lmtp when quota is full

2021-09-14 Thread Alessio Cecchi 

Hi,

on dovecot 2.3.16 with delivery via LMTP I found many of this error when 
a user have the mailbox full and personal sieve rules:


- lmtp.log:

If you can, I would get rid of MD5. It's no longer secure. Sending out
mountains of spam if a password gets cracked, could be problematic. :-{
I'm getting ready to drop using MD5 on secure cookies for that very
reason. Website software, not dovecot.

Hopefully that's helpful. I dropped one of my bare metal servers because
the company couldn't keep other spammers off of the IP block I was in.
They refused to do anything to clean up their blacklist, which included
me unfortunately.
