So are you saying that changing the "Mail From" header might be helpful?

But wouldn't this make all my email appear to come from me and I'd have to go into each email to see the original email? This doesn't seem very practical. As it is, most forwarded email is making it to my gmail account. If changing the Mail From will help further, it seems that would be the best overall solution for me. I'm looking for a solution that keeps me from having to build my own IMAP server and web front end that works most of the time. I'm open for suggestions for this novice user... ;) Thank you for your time and attention. Cheers, Drew
