I've had ISPconfig 2.2.25 (I know it's old) installed for a while now on a fedora9 box with multiple domains, everything worked fine! I needed to up the message size sending limit so I logged in and added: message_size_limit = 104857600 to the bottom of /etc/postfix/main.cf (su'd to root) then I just did: /etc/init.d/postfix restart But this seems to have stopped mail being delivered to all users If I telnet localhost 25 and do ehlo localhost I get: ehlo localhost 250-xxx.xxx.com 250-PIPELINING 250-SIZE 104857600 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So it's picked up the size change, but don't know why it's not not delivering any email, i've changed nothing else! Any idea's where to start?
I think I've solved it, I had changed the message_size_limit to 100MB, but if you don't also change the mailbox_size_limit to something higher it craps out. It doesn't tell you so when postfix restarts, you have to look in the /var/log/maillog So at the moment I've got a queue of about 20000 messages going through spamassassin and clamav System Load 1 Minute: 4.66 System Load 5 Minutes: 6.05 System Load 15 Minutes: 5.67 Whoops!
