    E-Mail

    In a faq regarding e-mail you mention that if an isp blocks port 25 traffic our only option is to use the isp mail server for outgoing mail.

    My current provider has port 26 open to allow outbound when 25 is blocked.

    Does the faq answer mean you will not allow/support any other port?

    cheers

      I do not get what you're saying. I believe outgoing smtp can only be on that port. I know my ISP blocks it and this is not a server issue but an ISP issue and I just use theirs when I am not at school.

          SMTP is "normally" on port 25 but does not have to be - it depends on what the server is set up to allow/support. As I said, my current provider supports port 26 also.

          If I use my isp's server the headers contain that information. I prefer if the headers only reflect my domain.

              Port 25 is the default and is the only SMTP port that we offer.

                  Port 26 is in no way standard, but how about port 587? See RFC2476. There are still situations where port 25 is blocked and the local SMTP server doesn't accept an outside sender address. The idea is that this port says "I intend to authenticate this message submission."

                  If not immediately, perhaps as needed or as part of future upgrades?

                      We do not use port 587 and it is not necessary.

                          My ISP (SBC Yahoo) recommends contacting my mail hosting provider (Dathorn) for info about using port 587. They go on to say, "Since December 1998, Port 587 has been the Internet standard (RFC2476) port for authenticated email submission for mail clients and is supported by most major mail hosting providers."

                          Meanwhile, I wait for SBC to unblock port 25. The reason I want to use the Dathorn for SMTP is because I want to SSL encrypt my email, and SBC won't let you do that.

                              This may be something that we implement in the future, but there are no plans to do so right now. RFC or not, a lot of hosts still do not offer this. And even for those offering it on port 26, many ISPs are now blocking that as well as 25.
