Both of the following I have experienced:
- Excessive spam and hacking from China. I blocked China. Then I got a client that did business in China and had a branch office there. Suddenly I cannot block login attempts from China. And the users complains loudly about the excessive reject rate of legitimate emails from Chinese customers due to the spam filters.
again:
- i am on the dovecot list
- i speak about dictionary attacks on POP3/IMAP
- reject rate is not a topic here
well, even if i would speak about the MTA it would not be a topic the MTA is a commercial spam-appliance and postfix not directly the MX
