My thunderbird client cannot connect to the IMAP server of gmail. After I have set up my gmail account in thunderbird, it is unable to fetch the messages from the mail server. Besides, I have enabled IMAP in my google account and also checked to allow cookies from third party. I have followed[link]. However, this does not work for me. I also tried resetting my iptables but that did not work out too. Can anyone help me out with this? Thanks in advance.

This is my iptables configuration. You may want to have a look at it. I don't know if anything is wrong about it.

Did you manually create those rules? I'd expect Linux distributions come up with reasonable defaults, so that receiving and sending email works out of the box. All email protocols (POP, IMAP, SMTP) run over TCP. You can look up the port numbers used on the servers in your Thunderbird account settings, and create firewall rules accordingly if needed.
