I'm sorry you're having problems... a few things...
1. I split this out into a new topic, because it really has nothing to do with the MOD. (check out the Read Me sticky)
2. If you're actually seeing an email come through and it has a Cc: address, then there's nothing wrong AFAIK inside TTX or even your server. TTX only constructs the document and pushes it out through your server's sendmail. Perhaps this is an issue with the recipient's mailbox? I assume you've already tried other email addresses for the Cc:?
3. I'm good with TTX, Perl and the TTX Modifications but I'm not really a server expert. Perhaps send a Ticket to Alex at his helpdesk just to be sure.
4. TTX v 3.0 has a Cc: option available. If you have the optional Layout Designer module, you can try with that and see if you get the same result. Though I would expect so.
I haven't had the chance to look further into this issue. The SMTP server I'm using is an Exchange 2003 Server, if that makes a difference.
I am aware that there is a CC option in 3.0 and I'm using it to notify operators when a ticket is updated.
I will try opening a ticket with Alex.
