I run several Drupal installations. Mostly 5, but still a few 4.7. All of them are using Drupal 4.7.0 including Contact and Webform 4.7.1
All work fine, except one. In the working installations when I get a Webform or Contact generated e-mail the sender is whoever sent the message.
In the odd installation there are two senders: the General Settings E-mail address and the actual sender. In mail.app the first (and wrong) sender also appears as reply-to address.
I have checked both installations and are the same, version wise.
I've tried to read the headers and understand the differences. I can see them, but I get nada out of them. I am hoping that one of the guys who really know their way around this can lend me a hand. I guess this has to do with server configuration. All my sites are at the same servers, but the one that is not working right.
With some luck I am not the only one in this predicament. I have tried the largely undocumented return path module, to no avail. I've spent longer hours than I should searching the forums. There must be a hack a patch, something.
After eliminating all common elements in the headers, the comparison is this:
********************************************************
Installation that works fine.
In this case, the Return Path and the envelope are the
username-of-the-site@the server
