My friend uses Thunderbird and he can't connect to his mail account on the server (my server created using Perfect Server tutorial). I checked his IP and it's listed on few blacklists. Is it possible that Thunderbird can't connect to my server (when click "Download" button) if my friend IP is listed? He can send emails, because his domain is on my server which is clear but he can't download emails.
Even if it's blacklisted, im theory it should still work. Did you check to make sure the incoming mail server is correct and responding?
I added Code: check_client_access inline:{friend_ip=ok} in postfix's main.cf file. Now it looks like (first few lines): Code: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_client_access inline:{friend_ip=ok} After this modification he can download and send emails.
