Any light anyone can throw on the 'nobody@myserver.com' address would be most welcome.

It is using the apache user @ your host name as the default. Try this: ini_set('sendmail_from', 'whatever@wherever.com');

I will try this but I do not understand why it should work. I have a 'From:...' entry in my headers. Why is this not being used as the primary from address and why is 'nobody@myserver.com' being added instead as the first from address ? In other words, I can understand if I supply no 'From:...' header entry that a default 'nobody@myserver.com' would be used but I do not understand why it is used even when I supply a 'From:...' header entry.

"From: " is used by your mail client to show who it's from. the ini_set (or you can set the 5th param to the mail() function) is a return-path. If the message bounces (recipient's mailbox full, server down, whatever the reason) it gets delivered to that address. They serve different purposes.

Does ini_set actually change the php.ini file in any way ?

No, it only affects the script it's running in. Comment it out. Check your mail server logs and/or apache/php logs to see if anything is going there.

You are correct. The mail server logs showed that a number of outgoing e-mails had been blocked because of an error. Once the outgoing e-mails were released I received my e-mail. It also turns out that the nobody@myserver.com was added to the header as the Reply-To address, not as a primary From address. I should have looked at this myself rather than taken the comment of someone else. I am still trying to investigate why AT&T e-mails are not being received but it may have to do with the outgoing mail server and is being investigated by my employer. I will wait on any further script changes until he tells me what is happening with the outgoing mail server. Thanks very much for your help.
