Disable SMTP TLS Authentication for some Users?

[gavinyoung]

Hi,

We would like to use MTA "TLS authentication only" for all our clients so SMTP authentication/sending is secure except we have some devices (mostly printers) that do not support STARTTLS.

E.g. Printer has "Scan to Email" feature and requires a SMTP account to authenticate and send from - SMTP authentication setting is possible but no option for STARTTLS or any connection security.

Is there any way to disable MTA/SMTP TLS authentication on a per user basis or is it only a global setting?

Any help would be greatly appreciated.

Regards,
Gavin

I have the same issue with a printer/scanner so would also appreciate help in this area. Thanks.
