Alternate POP3 and SMTP Port Numbers

Here’s another quick tip.

Some larger ISPs restrict the traditional ports for POP3 (incoming e-mail) and SMTP (outgoing e-mail) to only work with their own mail servers. This can be annoying particularly if you have your own domain name with e-mail hosting and you don’t fancy having to use your ISP’s SMTP server for a number of reasons including but not limited to:

  • arbitrary limits on the number of addressees,
  • arbitrary limits on the number of e-mails sent per given period of time,
  • susceptibility of ISP mail servers toward becoming blacklisted.

Anyway, most web hosts that offer e-mail hosting provide alternative port numbers just in case the standard ones are blocked. If you’re having e-problems with your hosted e-mail then this information might be useful to you:

  • POP3:
    • Default port: 110
    • Potential alternative port: 465
    • SSL port: 995
  • SMTP:
    • Standard port: 25
    • Potential alternative port: 587

Of course, these may vary between providers but you should find that this might work in most instances when stuck behind the imposed limitations of a given ISP.
