--- Comment #4 from davidc <[email protected]> --- 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:<[email protected]> << 250 OK >> rcpt to:<[email protected]> << 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:<[email protected]> >> RCPT TO:<[email protected]> << 250 OK << 550 Address [email protected] 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 [email protected] 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/ ##
