good. Can you provide details so that other people who get into the
same problem find the answer in the archives?
Well, it's very setup-specific...
The short of it is that I used to have my email chained inbound and
outbound through another server (for various reasons, including
keeping a full backup of all mail for me incase my own little rinky-
dinky server went down).
Then I changed this domain's inbound configuration so it went straight
to my server (basically just MX), since I'm really only using this
account for list mail, and I don't need a backup of that. When I did
that, I didn't change the outbound configuration, and the middle-man
server on the outbound route, which used to see the two addresses as
separate accounts, started interpreting mail from this address as
being an alias of another address, and added the Sender header (which
was what appeared in my mail).
The solution was simply to remove (comment out, in my case) the
relaying for this address from my Postfix configuration, and let it go
out directly.
The moral of the story is: Don't make configuration changes right
before you go out for dinner with friends who're in a rush while on 3
hours of sleep. =\
Cheers,
Neil.
