I don't understand. Many providers block the outbound 25 port because of their distrust of the infected computers of their end losers. What could possibly be their rationale for blocking the inbound 25 port?
- angry_octet 10y agoA lot of ISPs say you are not allowed to run 'servers' on your home internet, and hence block inbound low ports like SMTP, IMAP, http. It's just extortion.
