List of TCP/IP ports that should be opened for Xeams

Your firewall should allow traffic for the following ports:

Port Type Direction Description
Required IN/OUT SMTP traffic. This is used to receive and deliver emails to other servers on the Internet.

DNS traffic. Xeams will try to send a UDP query to the DNS server. If UDP does not work, a TCP request will be send.

Required OUT

Optional IN/OUT
In-bound port should be open if users are using POP3 to fetch their emails. Out-bound port should be open if you are using the POP3 fetcher.
Required if IMAP is enabled.
Required if POP3 server is enabled in SSL mode.
