I have a small DB with DBman. When using sendmail, some domains are getting the email while others are not. Addresses like @hotmail.com, or @aol.com are working, however the domain that is not working is @tamu.edu. Is this a DBman problem, or a problem with the host? OR is @tamu.edu returning the email b/c is is a mass email? How do you set up to recieve the emails that do not go through? Thank You!

Add something like
to your email script, or maybe try "Reply To" or "Reply-To" instead of "From" so that you'll get bounced messages. (Use your email address, or own custom variables instead of $apply_email).

I get bounced messages using the "From" on mine.
