Weird Sendmail problem

[joethong]

Hi,

I have a problem. I'm writing a script which will interface with
Sendmail to send out confirmation emails to new registered members.

The problem is only emails ending with a few specific
domain names will receive the email. Hotmail receives
the email but not some other domains like yahoo.com.

Why is this happening? I suppose it should have nothing to do
with the script.

Any help would be much appreciated.
Thanks.
Joe

Learn about DNS and this should solve your problem. there is another article somewhere on tek-tips that talks about yahoo rejecting e-mail that has an unresolvable address. research, my son, research.
