The issue turned out to be the format of the Plusnet username when one has more than one mailbox, i.e "username+fred"
This is fine when connecting to PN directly, but not remotely.
So my usernames are now set as "username+fred" for the incoming server but just "username" for the outgoing one.
Job done. Might be a good idea for Plusnet to add this to their setup guides - would save the sort of frustration I've had!
Kind regards

It used to be the case that ONLY the main account username could be used for smtp authentication. This changed some time ago and now a mailbox name ie. username+mailboxname can

be used as long as you use the mailbox password.

I've been using it since then, I have a dedicated mailbox and password just to use for smtp authentication to avoid using the main account details since the data is not encrypted.
Works fine on Thunderbird using a Linux netbook and the default mail client on a Nexus 7.

I've also used it in Portugal on both the Vodafone PT and TMN networks.

Firstly I've tested SMTP auth across six accounts from the internal network here using the credentials below:
bobpullen default account - successful
bobpullen additional mailbox - successful
boomboomer default account - successful
boomboomer additional mailbox - successful
johngie default account - successful
johngie additional mailbox - successful
I then tested the the following from my Vodafone HSDPA connection:
bobpullen default account - successful
bobpullen additional mailbox - successful
johngie default account - successful
johngie additional mailbox - fails
boomboomer default account - fails
boomboomer additional mailbox - fails
@boomboomer, I'm still of the opinion that we might be having problems with your account because it's not active yet. It will be interesting to see how things pan out when it is.
@johngie, I've just fiddled with your account (oo-er missus!) and will check in a short while to see if it's made any difference...

Seems to have done the trick. I can authenticate using your mailbox usernames now.
All that remains now is for @boomboomer to let us know whether or not the problem remains once their account is active ...
Edit: I've also raised an internal problem to ask that our engineers take a look into this in a little more detail (ref: 73618).

Greatly appreciated.
My only very slightly critical comment is that when I raised it with support directly they said it must be my authentication settings and left it at that - "contact the phone supplier".
You have gone that extra Yorkshire mile and sorted it. Brilliant.

John

Hi Bob,
I go live tomorrow, just changed all my domain redirects in advance - everyone will receive their email, but not be able to send.
Unfortunately I won't be at home when the broadband starts, hopefully the smtp server will authenticate even remotely then but it may need the ip check for the first connection.
I'll let you know how it goes.
Regards.

Quote from: Bob Edit: I've also raised an internal problem to ask that our engineers take a look into this in a little more detail (ref: 73618).
Turns out there was a bug in the software version we were using on the outbound anti-spam appliances. We've just finished upgrading them all to a newer build so I'm hoping the SMTP authentication oddities should now be a thing of the past.
For the record this also means my earlier assumption is false:
Quote from: Bob Seems like there might be some form of IP checking prior to an account being activated. That would also explain why you're able to send via Webmail (the connecting IP will be one of our Webmail servers).
