I would also suggest checking the machine's mail queue and mail service logs, and the sender and/or envelope sender's mailboxes for possible bounce messages. Hope that helps.	[reply]

It would be very helpful to see your code, or a shortened example that repoduces the problem. See also more hints on how to help us help you here. Having said that, if you're `open`ing `sendmail` and piping your mail there, that method is somewhat outdated and there are several modules to help you send email. See e.g. How do I send email?

Nothing like enough information here to form even a guess at an answer. 1 Peter 4:10	[reply]

Doesn't a new monk at least deserve a link to How do I post a question effectively? or I know what I mean. Why don't you?	[reply]

I am still unsure at this point if they would expend the effort to click on a link I posted. Don't want to overwhelm them with overly-high expectations. Not on their first day. 1 Peter 4:10	[reply]
