Add FROM info to bounce email envelope

[Andrew Cullen]

As part of an earlier question I found out that my ISP will not relay my 
bounce e-mails because the FROM portion of the envelope is left empty. 
My ISP is in no way going to assist me in my problem and I really cannot 
switch at this time so I'm looking for a solution. So... does anyone 
know how I can add some sort of sender info to the Qmail bounces before 
they go to qmail-remote? Do I have to hack qmail-remote.c directly?

Thanks

Andrew
