Subject: from address of cron emails

| Hi,
| I'm running cron through cygwin, using ssmtp.exe as the sendmail
| replacement. It seems that none of cron's e-mails are getting through,
| because my SMTP server rejects "root (Cron Daemon)" as a valid From address
| in the outgoing e-mail.
| Is there any way of changing this?

Interesting. You are the first to mention this, so there is probably a way.
Have you tried running ssmtp-config and setting FromLineOverride and/or
FYI ssmtp is called with the following command line:
"-FCronDaemon -odi -oem -oi -t". I think ssmtp ignores all of them except possibly -F
Still FYI, exim with the default conf file rewrites to
From: root@the.local.domain (Cron Daemon)

If you find a solution, please let us know.


Hi Pierre,

My solution was to make /usr/sbin/sendmail look like this:

sed -r -e 's/^From: root \(Cron Daemon\)\s*$/From:' | /usr/sbin/ssmtp.exe $@

It's a total hack, but it works.

I have FromLineOverride set to Yes, but I need it to be this way, so I didn't try changing it. My SMTP server is a local IIS SMTP server - it doesn't appear to rewrite the domain the way exim might. BTW, ssmtp doesn't ignore "-t" or "-oi".
