Marco.k Posted April 6, 2007 Share Posted April 6, 2007 I was wondering: Why do some ISP's allow inbound smtp trafic to ports like 587. I dont understand why a smtp server want to get it's mail deliverd on a other port than 25. (you cant say in a mx record you want your mail deliver at port x .. so) Normal other MTA's dont deliver mail on it and clients shut be or from there network or authenticated. Are there many more of these port where some mailservers accept mail to there domain ? Greatings, Marco. Link to comment Share on other sites More sharing options...
