RFC3834.pm checks for header 'x-auto-response-suppress'

[whity]

Hello,

The module RFC3834 is checking the header x-auto-response-suppress to detect if the message is an auto reply but, imho, this is not correct. From what I could understand, this header is to actually prevent auto-replies messages to the sender, in exchange servers, and not to identify the message as an auto-reply.

btw, thanks for the awesome lib :)

thanks

@whity Thank you for the advice regarding the X-Auto-Reply-Suppress header. I will review the code and fix it within a few days :-)
