Waitrose POP3 email problems

[#1]

Since early today I have been unable to send emails using POP3 on my Waitrose account.
I get the following error message:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'xxxxxxxxxxxx@waitrose.com'. Subject 'test', Account: 'xxxxxxxxx', Server: 'smtpmail.waitrose.com', Protocol: SMTP, Server Response: '550 relay not permitted', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
I have replaced personal info with xxxxxxxxxxx
Webmail works and incoming messages are getting through.
Any ideas please?

Hi Dennis,
I've asked Bob to have a look into this one, but that message is normally when you are trying to use an outgoing mail server that does not belong to your connection.
I take it you are currently connected to your Waitrose Broadband service?

Are you trying to send using your Plusnet connection Dennis? If not, that's probably what the issue is. I've just tried sending an email from your account and I didn't experience any problems:

$ telnet smtpmail.waitrose.com 25

You'll probably receive the auto-responder.

OE6 servers setting is showing  smtpmail.waitrose.com which I thought was right and has always been set to that both in my Greenbee & PN days.
I have only a Waitrose PAYG account just so I could keep my Waitrose email address. My only BB connection is my PN one.

That server address should be fine from a PN connection. In fact I've just tried sending an email from your account using my home Plusnet connection and I didn't encounter any problems.
Open up a command prompt and type.

telnet smtpmail.waitrose.com 25

Press enter and you should get:

Connection to host lost.
If any of the above fails, let me know at which point and what it says and we'll take it from there.

Bob,
After rcpt to:<support@plus.net>   I get 500 relay not accepted

[#7]

I have rebooted and changed my IP from 84.51xxx to 91.125 xxx and it now seems to work 

[#8]

That was going to be my next question
Will be interesting to see whether or not you have problems the next time you're assigned a similar IP?

[#9]

One step ahead of you Bob  

edit: I'm still on 91.125xxx this morning and it's still working!
