I have a form that allows users to register for seminars online. When they hit submit, it sends an e-mail to someone with all the details of the form using CDONTS.NewMail<BR><BR>This works fine on all e-mail addresses except the one I REALLY need it working on - my work address which is on a Quarterdeck mail server on the Mac. It works fine sending messages to Outlook or even Unix&#039s Pine, but nothing seems to get through to Quarterdeck Mail (I don&#039t get any error messages). I can send normal e-mails to this Quarterdeck Mail address from an external e-mail address.<BR><BR>This might be a bit of a long shot, but has anyone experienced something similar and know how to get it fixed?<BR><BR>Han.
