I hope this is the right forum to ask a configuration question (mutt and exim).
I'm able to send external emails from my linux-box as root with:
exim -f username firstname.lastname@example.org
But as local user I get a
550 Sender verify failed
back from my ISP because he got "user@localdomain" instead of "username" for verification.
I tried many configs like:
* set sendmail="usr/sbin/exim -t -f username
in my .muttrc (don't ask me why -t is necessary) and
in my /etc/exim.conf (after adding "user" to my /etc/group)
* How can I tell exim (and mutt) to let a local user "overwrite" the sendername (-f)?
Unfortunately I'm using very old versions of exim/mutt (1.92/0.91) and I'm not able to upgrade (but mailing works - at least as root).
BTW: I'm a single user on my box (thus I haven't security problems to allow all users everything).
