Sending mail from a non-Plusnet connection - SMTP authentication
I guess we'll count that as official then 
By the way, the article finishes with
which should really continue 'unless they block connections over port 25 to anywhere other than their own smtp server'. Three mobile is an example - you have to swap & send via their own server. Not too much of a hassle if you use Thunderbird, but a real pain if using multiple accounts with some other email clients.

You can use telnet to check for responses on any port - relay.plus.net does not respond to port 587.
Quote from: MJN Do three block the SMTP submission port 587? If not, can Plusnet enable that? Of course, please only do so if you are also providing TLS encryption.
We've no immediate plans to open up port 587 or enable TLS encryption I'm afraid

That seems like a real shame given that most decent ISPs have been doing this for upwards of 6 years. (I had thought of Plusnet as a decent ISP by the way, and have been with them for as long as I can remember, stayed with them for 4+ house moves and made many referrals)
I have my iPhone on Orange and have never had any problem sending email through plus net using my user & password for authentication. But I now have an iPad on Three, and they block all port 25 smtp servers except their own, and their own is staggeringly unreliable. Even when I get an email sent, it often returns as undeliverable. Drives me mad after being used to using plus.
Plus net, you must have hundreds of customers who have phones or mobiles devices like iPads or tablets on the Three network and since they allow port 587, surely it's time to catch up with the rest and help out your customers at the same time??? Please?
Have you got connection security set to None and Authentication method set to Password, transmitted insecurely?
If so it should prompt you to enter the password the first time you try to collect mail (and there's a tick box to save the password).
