I just installed it on a machine that wasn't yet fully installed and this
is the only configuration of ssmtp (/etc/ssmtp/ssmtp.conf):

# /etc/ssmtp.conf -- a config file for sSMTP sendmail.
# The person who gets all mail for userids < 10
# The place where the mail goes. The actual machine name is required
# no MX records are consulted. Commonly mailhosts are named
# The example will fit if you are in domain.com and you mailhub is so
# Where will the mail seem to come from?
# The full hostname


I think this would make it clear enough (no I have not tested it yet, I
don't have the ability right now).

And this was taken from the /usr/doc/ssmtp/README.Debian:

ssmtp for DEBIAN

This is a secure, minimal mail sender.

This is basically a package that is abandoned. I have fixed it up so that
it works under Debian/GNU. Do not expect any upstream upgrades.

There is one configureation file in /etc/ssmtp/ssmtp.conf where all
are set.

Header size is limited to 4K. Do not try any mass mailings with this
package. Moreover the number of recipients is limited to 100.

sSMTP also supports reverse aliases if the file /etc/ssmtp/revaliases is
present. See ssmtp(8) for details.

So it does have limits (this was taken from current Debian stable !).

hope this helps,

New things are always on the horizon.
