I'm using Outlook Express on Windows XP (SP3). Recently I lost the ability to relay mail directly through my e-mail host via SMTP-AUTH, so I switched to using my ISP's relay. That required me changing the SMTP settings of course, and they also require SMTP-AUTH. For some reason, Outlook Express is putting the authentication name from the SMTP-AUTH into the header as my e-mail address (which is completely wrong!). The account e-mail address is set properly, but Outlook Express seemingly ignores it. I went ahead and also set the reply-to address, and that gets set properly in the header (but the "From" is still wrong!).
Example of what someone sees in the header when receiving e-mail from me:
From: Brian Knoblauch <smtprelayaccount@myisp.com>
Reply-to: Brian Knoblauch <brian@myemail.com>
Any ideas on how to force Outlook Express to use the mail address for the uh, mail address? :-)
2Perhaps it's not Outlook Express that's putting the wrong e-mail in the From line. Maybe your ISP's relay is putting it there? Or perhaps an e-mail scanning program on your computer is changing the From address? Try sending a test e-mail in Outlook Express, then look in the Sent Items folder to see what it looks like there. (To see the exact headers, right click on an e-mail in the list, choose Properties, then click on the Details tab.) – Bavi_H – 2010-08-11T00:44:30.257
It's definitely Outlook Express. My Vista machine with Microsoft Mail is setup the same way, but the header information comes through set correctly. There's no e-mail scanning software installed. – Brian Knoblauch – 2010-08-11T12:07:15.357

Hm. I'm running out of ideas. The last thing I can think of is to try removing the account and re-creating it again from scratch. (The initial symptoms you described suggested something besides Outlook Express was changing the From address, but the further details don't paint as clear a suspect as I had hoped.) – Bavi_H – 2010-08-13T00:53:13.717
Conveniently enough (well, not really) the hard drive in that box failed and I got to reinstall XP fresh. All patched up, and it does exactly the same thing. Sigh. – Brian Knoblauch – 2010-09-08T19:27:41.443
Well, my e-mail provider re-enabled SMTP-AUTH, so I was able to discontinue using my ISP's SMTP relay. Back in business, but never did figure out WHY it was acting odd when using the local ISP SMTP relay... – Brian Knoblauch – 2011-07-07T14:04:08.517
