Package: ssmtp
Version: 2.64-9 amd64
A new lxd container with debian testing/bullseye has to send emails to
a SMTP-Relay. The chosen software is ssmtp 2.64-9 and the configuration
looks like that:
(not auth internal relay)
/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]:mailout.example.com
www-data:[email protected]:mailout.example.com
/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 ...
mailhub=mailout.example.com
# Where will the mail seem to come from?
#rewriteDomain=
# The full hostname
hostname=srv0815
# 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
I can send an email as following and everything looks like expected:
www-data@srv0815:~# echo "Test message" | mail -s "Test message - is
from?" [email protected]
But if I send an email with an additional "from address" like this...
www-data@srv0815:~# echo "Test message" | mail -s "Test message - is
from?" [email protected] -a From:[email protected]
...I will receive the email with the given "From address" (e.g. From:
[email protected]). But this shouldn't be possible!? I've
explicitly set "FromLineOverride=NO" in my configuration. Therefore, as
far as I know, ssmtp should ignore any additional "from address".
The same configuration works as expected on another container with
gentoo linux (its ssmtp-2.64-r3 here). Probably the same upstream
version.
Also, I've tried an older ssmtp version on the same lxd container:
ssmtp-2.64-8.1+b1
With 2.64-8.1+b1, no issues. The additional from parameter will be
ignored correctly.
I think it could be a bug in the current testing version of ssmtp.
Best,
René

This command does not work.
$ echo "Test message" | mail -s "Test message - is
from?" [email protected] -a From:[email protected]
-s option is not handled by ssmtp
-a is of no use unless paired with -au for the authentication user or
-ap for the authentication password.
To effectively test the command you will need this:
echo "Test message" | ./ssmtp -d -f [email protected] [email protected]
The -f option replaces the from address.
Closing the issue.
