Re: Having Strange Problems sending email.....

Thanks for the reply :-)

The Yahoo user did check his bulk mail folder each time and nothing was
there. My first thoughts about the issue was that it would be a user filter
issue so it was the first thing I looked into. Because he was able to
receive the same emails from the same email address/domain the conclusion I
came down was that it was not his spam filter settings.

The only difference between the successful and unsuccessful deliveries is
that with the delivered emails - they initiated with my home computer and
were then sent through the same mail server and accounts as the unsuccessful
ones.

It must be filtered in the manner you suggested - according to routing. My
home system is in Canada and the site issuing the emails is hosted in the
USA. I don't know enough about email routing to understand the difference
between the two. For instance, when I send from my home computer it just
connects to the same mail server in the US that the forums use. So I would
have thought that all routing would be seen as the same by the Yahoo
service. My understanding is that the mail server in the USA connects to the
Yahoo server and delivers the mail - whether or not the mail originated in
Canada, the US or anywhere else where mail is sent via my mail server in the
US.
