Non delivery of emails

[Guest]

Some of our emails are not getting through to recipients but we are not
getting any failure messages from our provider, pipex. We, therefore, don't
know when they don't get through. We can send mail successfully from
netmail. PIpex say that there is nothing wrong from their side and it is an
outlook problem ie there is something in the emails which causes them not to
arrive. We have changed nothing - this problem started two weeks ago. Any
ideas what we can check in outlook?

Is there any pattern to the mail items that don't arrive? Are they to the
same recipients or in the same format?

We use outlook in a very basic way so all messages have the same format.
They are not getting to a number of different recipients - some large
companies, some individuals.

For some reason I saw you reply but it 'disappeared' from my newsreader.
Could you please resend it?

Thanks

No problem. Here you go -

Is that format HTML or Plain Text?

Try Plain Text as a test to see if the item gets through to at least on of
the people not currently getting mail from you.

Thanks, we will give that a try. We have now found out that at least one of
the people we were trying to email found that that the email had arrived on
their system but had been filtered out by the spam filter - message labs. We
think this might have happened in the other cases and are trying to find out
why, all of a sudden the spam filter rejects our messages. We don't know if
it is because of the provider, pipex, the spam filter, message labs, or
outlook. All the non recipients have had messages from us before.
