Is there a possibility to change the behaviour when a mailserver rejects
empty "mail from"
I know that according the RFC's people should accepts an empty return
path, but a lot of servers reject
Mail from:<>
As a result the callout fails ... but I want to know if this is tunable
E.g. consider the rejection below as a defer
Mail from:<>
501 Syntax error in address
E.g.
Mail from:<>
250 OK
Rcpt to:<test@???>
550 5.1.1 <test@???> is not a valid mailbox
Is there a possibility to differ between those 2
Thanks
Ronny
