BT Broadband’s OTT SMTP Requirements

January 18th, 2008 Leave a comment Go to comments

BTSince the advent of spam, most ISPs have their SMTP servers set to only accept non-authenticated connections from computers on their own networks, and justifiably so. Some (mine included) offer the additional extremely useful option of making an authenticated connection (username and password) from outside their network to allow you to still use their SMTP server from anywhere in the world, without having to change settings to your host ISP’s SMTP server. In both cases, I am free to set the “From:” field to an email of my own choice, as I don’t use the email address provided by the ISP – I have my own domain name(s) for that, and want my outgoing emails to correctly show them instead.

Not so with BT Broadband. I was asked to assist a colleague who was complaining that he couldn’t send email on his BT Broadband connection. To cut a long story short, BT Broadband firstly require you to log in to the SMTP server using authentication, even if you are connected via their own network. Why?

However, that is still not enough if you don’t want to use the silly ‘surname9876@btinternet.com’ address they supply you with. You must also register every single ‘from’ address you wish to use via BT Yahoo first.

Makes me so glad I have a decent ISP.

Further information on how to set things up correctly on BT Broadband can be found from Paul Doherty and Peter Curtis.
