Αντικείμενο: [exim-dev] [Bug 2604] exim does not send DATA to target host when verify callout hold and delivery cutthrough
https://bugs.exim.org/show_bug.cgi?id=2604

Hi Jeremy,

Doing only cutthrough means the sender only gets "550 Administrative
prohibition" to RCPT rather than any useful error (e-mail address doesn't
exist, user is over quota etc) and I don't see an option to change this.

The specification also mentions a couple of scenarios in which cutthrough
cannot be used, in such cases we would like to at least have already performed
the recipient verification so we can reject, rather than queue and then bounce.

I forgot to mention above, in case it is not obvious, removing "hold" from the
verification options means everything works fine. (Although weirdly it then
makes *three* separate SMTP connections with the target host, two verifications
for the same recipient and then one for the actual message. But this is a
suitable workaround for now).

Thanks
David
