I just set up my mail server using postfix / dovecot / mysql and it
works well. I just have a problem : I'm a trying to have a overquota
notification and the server sends nothing (mail server rejects incoming
mail).
What do you mean with "the server sends nothing" Which server should send
what? And should the mail _not_ reject incoming mail, if the user is over
quota?
If you mean: /usr/local/bin/quota-warning.sh is executed, but postfix does
not deliver the warning, because the user is overquota; then you need to
make the script deliver the message in alternate ways:
a) use Dovecot deliver directly with quota disabled
b) spool the message into Maildir directly
Could you tell me if there is a problem with dovecot or postfix configuration?
postfix+quota config usually contain a quota-status section, like
described here (German, but the code snippets are significant):
