[Firehol-support] Reply pop3 packets being dropped

[Martin Kong]

We are using firehol on our pop3 server.  I'm seeing these log entries from time to time.  Seems like some reply pop3 packets are being dropped.  Am I reading these logs correctly?  What would be causing it?

Some people are complaining they have problem receiving email from our pop3 server (it happens may be 3-4 times a time).  I wonder if this could be the cause.

I have turned off all the protection.  Config only allows server pop3 and no client pop3. 

x.x.x.122 is our pop3 server IP, x.x.x.28, x.x.x.168 are IPs of client machines trying to receive email from the pop3 server.

Thanks in advance.
