How to get ssmtp to map local user to email address for the To: field
I have struggled a bit with ssmtp
too. The first thing I learned is that the aliases mechanism does not work with the plain mail
program; I have to use mailx
from the package bsd-mailx
— never knew why. So before starting to change configurations around check with it.
Anyway, as a reference, I have a working ssmtp
setup like the following:
file
/etc/ssmtp/ssmtp.conf
:# # Config file for sSMTP sendmail # # The person who gets all mail for userids < 1000 # Make this empty to disable rewriting. [email protected] # The place where the mail goes. The actual machine name is required no # MX records are consulted. Commonly mailhosts are named mail.domain.com mailhub=mymailserver.mymail.domain.com:25 # Where will the mail seem to come from? rewriteDomain=mymail.domain.com # The full hostname hostname=myhostname.mymail.domain.com # Use SSL/TLS before starting negotiation UseTLS=No #UseSTARTTLS=Yes # # Are users allowed to set their own From: address? # YES - Allow the user to specify their own From: address # NO - Use the system generated From: address FromLineOverride=NO
file
/etc/ssmtp/revaliases/
# sSMTP aliases # # Format: local_account:outgoing_address:mailhub # # Example: root:[email protected]:mailhub.your.domain[:port] # where [:port] is an optional port number that defaults to 25. # root:[email protected] romano:[email protected] postmaster:[email protected]
and now it works:
[romano:~] % mailx -v root
Subject: test
test
.

I have a simple
ssmtp
setup.The command
echo test | mail -s "testing" username
always results in me trying to send an email tousername@hostname
which always fails.I am thus trying to map the local username to a specific email address.
How do I do this?
I tried
/etc/aliases
, but$ sudo newaliases newaliases: Aliases are not used in sSMTP
Then I tried
$ cat /etc/mail.rc alias root root<[email protected]> alias username username<[email protected]>
But it still isn't working. Any ideas?

Ikrom about 5 yearsThanks, it worked after I added

line to/etc/ssmtp/revaliases

Hoffmann about 4 yearsThis only works for the From-address. If you want to change the To-address you have to edit
/etc/mail.rc
