Port 25 is SMTP, it needs to be allowed in outgoing direction. Otherwise you will be locked to proprietary web mail.

- namibj 7y agoThere's a dedicated SMTP submission port. Try dialing e.g. gmail's MX record on 25. It might/should probably block.
- anticensor 7y agoIf you mean port 465, it is the port for SMTPS, not a dedicated submission port. I received timeout, not block, when I queried gmail on port 25. If it were blocked, I would get a TCP reset.
- vidarh 7y agoPort 587. Not nearly all consumer isps block port 25, but a lot do.
