IMAP gmail seems blocked from any-trusted to any-external
Hello to all,
I have the mail clients (Oulook 365 and Outlook) that are blocked by the firewall to access to imap.gmail.com via IMAP/993 (I checked it by telnet command line). I already tried to add a policy from any-trusted to any-external, TCP port 143 and 993 (tls), but it seems doesn't work fine. In true I don't understand because I need this policy (If there are no blocks, all outgoing traffic must go...out). Is there somebody that can help me to find a solution? WatchGuard firewall is really hard to manage and to understand.
