I've noticed a lot more smtpd threads running lately than normal. I've also noticed that occassionally the server seems slow (even though top shows it running fine). I'm wondering if I'm not getting overwhelmed with spam.
Specifically, I get a lot of bounced emails to wrongaddress@mydomain.com as a result of spammers using my domain in their headers. So my logs have a lot of this:
Recipient address rejected: User unknown in local recipient table;
Which is what I want I think.
Is this possibly slowing my server down? Is there an easy fix to this if so? I'm also curious if the way it's working is the best way, i.e. if the user email address isn't whitelisted, I drop the email with the least amount of fuss.
