Exim gotcha with SMTP Auth
One gotcha when using exim to do authenticated SMTP one wonders why you keep seeing the following:
Return-path: <"email@add.re.ss"@server.host.name> *snipped* Sender: "email@add.re.ss"@server.host.name *snipped*
One needs to modify your acl for acl_check_rcpt for authenticated SMTP connections to contain the sender_retain bit like below:
accept authenticated = *
control = submission/sender_retain
Restart your exim (in my case on FreeBSD I used /usr/local/etc/rc.d/exim restart) and send a email:
Return-path: <email@add.re.ss> *snipped* Sender: email@add.re.ss *snipped*
