https://bugs.exim.org/show_bug.cgi?id=2604 --- Comment #9 from davidc --- Hi Jeremy, Indeed, it would be preferable that, if a message is to be rejected for any reason (including after DATA), that rejection is passed back to the sender's SMTP connection, rather than accepting and sending a bounce (and the consequent problems with backscatter and reputation).

https://bugs.exim.org/show_bug.cgi?id=2604 --- Comment #8 from Jeremy Harris --- Hmm, you're right; I was misremembering. The copy-through only applies to the data phase; as the original calout mech is being used for the cutthrough delivery startup all of its behaviour remains. Back to the previous - presumably you want the cutthrough data-time semantics so only doing the callout,hold does not help? -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##

https://bugs.exim.org/show_bug.cgi?id=2604 --- Comment #4 from davidc --- With recipient verification removed and only the cutthrough accept line present: >From sender to inbound relay: << 220 smtpin001.a.snlmail.net ESMTP >> ehlo asd << 250-smtpin001.a.snlmail.net Hello sarlonintman001.sargasso.net.uk [2a05:e200:0:1::1] << 250-SIZE 52428800 << 250-8BITMIME << 250-PIPELINING << 250-CHUNKING << 250-STARTTLS << 250 HELP >> mail from: << 250 OK >> rcpt to: << 550 Administrative prohibition >> quit << 221 smtpin001.a.snlmail.net closing connection >From inbound relay to mailstore host: << 220 mailstore001.a.snlmail.net ESMTP >> EHLO smtpin001.a.snlmail.net << 250-mailstore001.a.snlmail.net Hello smtpin001.a.snlmail.net [2a05:e200:1:74::2:1] << 250-SIZE 52428800 << 250-8BITMIME << 250-PIPELINING << 250-CHUNKING << 250 HELP >> MAIL FROM: >> RCPT TO: << 250 OK << 550 Address inva...@sargasso.pw unknown. >> QUIT << 221 mailstore001.a.snlmail.net closing connection So the sender just gets "550 Administrative prohibition"; even if smtp_return_error_details is turned on at the inbound relay, it is hiding the error. Whereas when recipient verification is used, they get 550-Callout verification failed:" "550 550 Address inva...@sargasso.pw unknown.". -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##

[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 --- Comment #2 from davidc --- 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).

https://bugs.exim.org/show_bug.cgi?id=2604 --- Comment #1 from Jeremy Harris --- If you're going to do cutthrough delivery there is zero point in separately specifying a recipient callout. Not to say there isn't a bug here, but you are making it needlessly complex. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
