Deliver time is very slow (many minutes)
I have CentOs 4, vpopmail 5.4.9, mysql 4.1.7
What would i check?
It might be trying to deliver to a Maildir that has a huge amount of
mail in it.
I would check your qmail logs to see if one account is being delivered
to, over and over. Then check that Maildir and remove the email.
Also check the .qmail-default file and set the default delivery to
be either bounce-no-mailbox or delete.
