[ubuntu] Firewall blocking too much.

view story

http://ubuntuforums.org – Hello, Today I finally decided to configure a firewall. Everything seemed to go well, but now I can't seem to send mail from thunderbird, gmail imap mail. The port I have set for my mail is 993, which is by default. In my firewall setting I allow both udp/tcp connections going out on that port. I use GUFW for my firewall config. It seems that I can still receive mail, but not send. I know it is the firewall, because when I disable the firewall I can send mail fine. Thanks, Kopkins (Hardware)
