Is there anyone here who uses plusnet as an ISP, getting three copies of
each emails sent to them?
We use XenCentric as a domain hoster and PlusNet as an ISP and for the last
four weeks when XenCentric tries forwarding our emails to Plusnet they error
so xencentric retries but they actually are getting through each time.
Anyone else using XenCentric as a domain hoster and PlusNet as an ISP?
PlusNet say they don't have a problem with other people forwarding and
XenCentric have no problem with other ISPs and have sent me the logs below
showing the PlusNet error.
I eventually persuaded plusnet to report the fault to the netops team (They
opened a ticket but did nothing until I chased them, maybe they were hoping
the problem would just go away!) by the time they investigated they said the
info was too old and they are being sent three copies, the last request is
for a set of recent emails with headers.
I've told them:
Asking for the email headers again demonstrates that they have fundamentally
misunderstood the problem. YES my hoster sends the emails THREE times BUT it
is because your servers is FALSELY reporting an error each time, when it has
actually successfully received them, that is the issue. (Another set of
emails with headers will provide no information about the errors from your
server) It is the logs from my hoster that are the thing they need to be
looking at. Please confirm they have copies of the two logs from my hoster
previously sent.

Our server tries the two MX records for
mx.core.plus.net until one
accepts the email. The first two attempts always seen to fail, but
there's no further information on why this is.
