554 error to 1 & 1 hosted domain

There was an old thread on this topic, apparently now locked.

Mail sent by me to a friend with email address on a domain hosted by 1 & 1 is generating responses like

Final-recipient: rfc822;
Diagnostic-Code: smtp; (mxeue112) Nemesis ESMTP Service not available

The mail is apparently delivered, though.  A message from her to me received a similar response and was not delivered, although we originally assumed this was because it contained just a single URL which I wanted.


I can provide the full error message if required but I will need to spend a little time redacting the meaningful addresses and names.

Re: 554 error to 1 & 1 hosted domain

Hi @Shentar,


Is your email service provided by ourselves, or a third party (for example a domain hosted elsewhere/Gmail/Hotmail etc,)? 


I'd also suggest it would be useful to provide a header if this was at all possible.
