| Hi Pierre,
|
| My solution was to make /usr/sbin/sendmail look like this:
|
|  #!/bin/sh
|  ARGS=$@
|  sed -r -e 's/^From: root \(Cron Daemon\)\s*$/From:  Administrator@mydomain.com/' | 
/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".

Thanks. What does your SMTP server object to:
- the format with the ( ) ?
- the fact that root is not a Windows user ?
- the fact that there is no domain?

Pierre
