[SM-USERS] login very slowly after iptable firewall is on

[Tommy Tang]

Dear All:   I have installed SquirrelMail 1.4.5 on Redhat Enterprise Server 3.0 and everything is OK untill I enable the iptable firewall. After the firewall is enabled, the login comes out just as usual, but after clicking the login button there is nearly no reponse for about 6~7 minutes for the login result window to comes out. If I stop the iptable firewall everything restores to normal. What's the problem? BTW, my IMAP server is the RedHat built-in IMAP server.   The mail server is: http://mail.vigoicu.com:8080   Best Regards! Yours Sincerely Tommy
