Hi
we want to use sendmail due to formatting plugin we use.
It was working for few months but stopped working.
We can send mail via smtp to our SMTP relay.
when we use sendmail the mail go to public SMTP relay (e.g.mail.global.frontbridge.com ). How can we configure it?
(didn't find /etc/mail etc.)

Thanks
Matty

The following link will give you a rough idea of how to do this, just note that you do not need to use the blogs sendEmail binary, you just need to give the correct path to sendmail.
