[Dovecot] per-network auth mechanisms

[George Moury]

Hi All,

I need use different auth mechanisms for different IP-address of 
IMAP/SMTP SASL clients (allow plain authorisation only for my own 
network), but there is no examples at wiki.dovecot.org for this feature.

Is this feature available at rc19 version?

Thank you in advance.

Best regards,
George
