Sorbs can be devilish and you should be concerned. My first question to
you
though is do you have a signup process and does it have a captcha? If you do
and do not include a captcha, you should first resolve that by installing a
captcha.
Most likely sorbs will say that they have an email that p

Override this default using transport_maps.

It is something that is widely used on the Internet.

Can we abuse A-records to load-balance in the same way MX-records have been

AS COCUMENTED the domain parameter takes multiple domains.

This is a list of domain names, paths to files, or dictionaries.
When specified, only fully qualified search

Hello,
I have to add a "Reply-To" Header in (smtp-) submitted messages.
Adding it unconditionally using PREPEND result in messages with more
then one instance
of this header which violates RFC5322.
Is there a way to add a header _only_ if not present?
