On my laptop, I use mutt with postfix for sending e-mails, and
fetchmail for receiving them. Postfix is setup to relay mails through
gmail. I am the only user on the computer and all mails originating
from the computer are sent from my account.
A limitation of the present setup is that it sends e-mail only from a
particular gmail account. I have, like most people these days, a
couple of different e-mail accounts that I like to use for different
purposes. I would like to set up mutt and postfix in such a way that I
could use these various accounts for sending mail. I have set up mutt
profiles for different accounts. With that mutt is able to send mails
with different "From:" headers.
But since all mails are passed on to postfix from my user account,
they are all treated as coming from vi...@localhostname. Postfix
ignores the From address put by mutt, and treats it only as coming
from vi...@localhostname. It then delivers the mail using only sasl
password authentication from one account which has been set up to
handle all general mail. The sasl password authentication file also
has details for other accounts but since postfix does not treat the
mail as coming from those account, it does not use the sasl password
authentication for them. In other words, since all mail is treated as
coming from vi...@localhostname, they go through the same sasl
password authentication, and therefore are sent as coming from the
same sender account.
I do not know if I have been able to make myself clear. I shall be
more than happy to clarify again if I have not been able to.
I am appending my /etc/postfix/main.cf
I shall be happy to provide (samples of) other configuration files, if
necessary.
I shall be grateful if anyone could point me to a useful guide on the issue.
