POP server takes forever

[datamike]

Hello, I have been using a Qmail server for a few months and it works fine when we use the internal IP address to recieve POP mail but now I need people to be able to check from their mail from the public IP address and it takes forever for it to go through. In Eudora, I can see the yingyang thing spinning for like 20 seconds, then it downloads the new mail . I don't know why it takes so long. I have a openBSD firewall that passes port 110 through so I don't think that is the problem Anyone have any ideas on what to check? Thanks.

This is a well known issue:

I solved this by reconfiguring my firewall to drop incoming identd requests (port 113) instead of blocking them.

Hi Cloverm, I had
block return-rst in on $Ext_iF proto tcp from any to any port = 113
Into my firewall all along, it did nothing. I tried adding the -R into tcpserver, I guess the -R stops AUTH
/usr/local/bin/tcpserver -R
Nothing. It is still super slow. Do you think it could be something else?

Just to let you know I changed it to
usr/local/bin/tcpserver -RH 0 110 /var/qmail/bin/qmail-popup
and I had to reboot in order to get it to work. I guess restarting the mail server was not enough to get the changes to happen. Thanks.
