I have a simple ssmtp setup.

The command echo test | mail -s "testing" username always results in me trying to send an email to username@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<xxx@yyy.com>
alias username username<xxx@yyy.com>

But it still isn't working. Any ideas?

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:

  1. 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.
root=romano@mymail.domain.com

# 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

  2. file /etc/ssmtp/revaliases/ 

    # sSMTP aliases
# 
# Format:   local_account:outgoing_address:mailhub
#
# Example: root:your_login@your.domain:mailhub.your.domain[:port]
# where [:port] is an optional port number that defaults to 25.
#
root:romano@mymail.domain.com
romano:romano@mymail.domain.com
postmaster:romano@mymail.domain.com

and now it works:

[romano:~] % mailx -v root
Subject: test
