Standard for most ISP's. You should be able to use port 587 (Secure SMTP) which pretty much every provider support. If you're setting up a mail server then stop, take a breather then set this up on a dedicated VPS somewhere (like Linode or AWS) or go to another platform like Google Apps, Office 365 or Zoho Mail.

Hi Michael,

Thanks for the reply, tried 587 as well which didn't appear to work - remote support for my daughter isn't easy.

Cheers,
Mark

BigPipe have previously said they don't do port blocking. Has this changed?
