Betreff: [exim] greylisting problem with Exim 4.50 as remote MTA
Hi there

The sysadmin of an Exim 4.50 installation tells me that Exim does not
differentiate between a 4yz and a 5yz received after the DATA transfer, i.e.,
treats them both as permanent errors and so bounces the message. Hence
interoperating with DCC greylisting is impossible. I know for sure that Exim
4.34 does not suffer from this (alleged) protocol violation.

Any comments?
