how to allow mobile user to send email with getting blocked

[Markus Nilsson]

In postfix I solve this by setting
smtpd_sasl_authenticated_header = yes That by-passes network checks in SA if the header comes from a trusted source, and the host receiving the connection from your remote users is trusted I guess?

This disables RBL-checks at SA, if you need even more negative scoring, you can modify the score for ALL_TRUSTED

Didn't find that one in my search, thanks.

Not sure I understand fully, I use postfix and haven't touched sendmail in 
years. Are you suggesting adding an additional header at the mail client
level that is then processed by the mta/ms?

I'n not convinced that's something I can fully control on the various mail 
clients on the phones, it's just the same as using ssl client certs. Not all
devices support it.
