I emailed 1and1 again and told them that we had changed the SMTP to mrvnet.kundenserver.de, and that worked; this is their reply:
The server mrvnet.kundenserver.de is an alternative SMTP server if auth.smtp.1and1.co.uk does not work. It is actually advisable to use mrvnet.kundenserver.de as the outgoing server if you are sending mails through scripts.
Apologies for the inconvenience caused.
So no need to change anything in the scripts, we should all just carry on with mrvnet.kundenserver.de.
