Hello all:   Quick question about mail delivery times and some issues that we seem to be having:   1.  I'm running FreeBSD 4.11 using MySQL auth.  The version of Courier is a bit older - its 0.43, but this system has been very stable over the past couple of years, so we're not looking to upgrade unless its absolutely necessary.   2.  We have five hosted domains and 2 routed domains on the machine.   The routed domains receive their e-mail with no delay at all.  We do have around 6000 messages a week in the postmaster account due to spammers sending messages to non-existent users at the routed domains.  I'm unsure how to resolve that issue and it may be part of the cause of our "real" problem.

The hostdomains seem to have HUGE delays in receiving their e-mails.  One e-mail sent at 8am doesn't actually get deposited in the user's Maildir until 3pm.   Is there a setting or a series of settings that can force the e-mail arriving for the hosted domains to move quicker?  Am I missing something? 

The only "real" problem is the hosted domains don't receive e-mail quickly at all - the messages seem to stay queued for hours and I've tried using the courier flush command every 5 minutes from cron - still doesn't help...   Thanks for any suggestions...
