Should not the Postfix SMTP client read the 221 as a positive
response to RCPT TO, and consider the recipient as "deliverable"?
I looked into this, and found that my SMTP transcript differs.
When I turn on verbose logging (with
"debug_peer_list=mail.global.frontbridge.com") then this is logged:
S:220 VA3EHSMHS018.bigfish.com Microsoft ESMTP MAIL Service ready

C:EHLO spike.porcupine.org

C:RCPT TO:<postmas...@frontbridge.com>
C:RSET
C:QUIT
S:221 2.0.0 Service closing transmission channel
Which means that Postfix reads the 221 as a positive reply to "MAIL
FROM", and that Postfix reads EOF instead of the reply to "RCPT TO".
That is also consistent with my logging (lost connection with
mail.global.frontbridge.com[216.32.180.22] while sending RCPT TO).
Victor, can you check this?
