mail problem

hi,

i have an intermittent email problem. the log reports the following.

2006-10-10 13:47:03.808227500 delivery 400: failure:
Connected_to_194.73.73.217_but_sender_was_rejected ./Remote_host_said:_550_<(E-Mail Removed)>..._Not_ permitted/

We are sending all email via our ISP mail relay server.

Any help appreciated.

They're not accepting email from you, for reasons known only to them and
possibly you.

OK, thanks. but the problem is intermittent. Is that not weird?

No, it's not, depending on the software they are using to generate the DSNs.
It might be their MTA or a client application designed to impersonate an
MTA.
