Summary: cutthrough_delivery / cutthrough_delivery conflict
Product: Exim
Version: 4.82
Platform: Other
OS/Version: Linux
Status: NEW
Severity: bug
Priority: high
Component: ACLs
AssignedTo: jgh146exb@???
ReportedBy: exim-users@???
CC: exim-dev@???
In my remote_smtp transport I have:
hosts_require_tls = <; fc00:beef:beef:601:9530:2068:3df9:5cb7
I just added this to the top of my rcpt ACL:
warn control = cutthrough_delivery
Now I'm getting this in my mainlog whenever a message is delivered:
2013-10-30 12:16:18 a TLS session is required for hype.glue.grepular.com
[fc00:beef:beef:601:9530:2068:3df9:5cb7], but an attempt to star
+t TLS failed
The message *is* delivered using a TLS secured connection though:
2013-10-30 12:16:20 1VbUh8-0006Mc-Po => mike.cardwell@???
P=<mike@???> R=relay_remote T=remote_smtp S=758 H=hype.glue.gr
+epular.com [fc00:beef:beef:601:9530:2068:3df9:5cb7]:25
X=TLSv1.2:DHE-RSA-AES256-GCM-SHA384:256 CV=no
+DN="/description=TN8sb87Rblzkc66S/C=GB/CN=glue.grepular.com/emailAddress=postmaster@???"
C="250 OK id=1VbUhz-0008Cg-3H"
I see no errors in the mainlog of the destination server
(glue), and a tcpdump shows that this is what happens during the
cut-through delivery attempt:
<= 220-glue.grepular.com ESMTP Exim 5.99 Wed, 30 Oct 2013 12:28:38 +0000
<= 220 BOOSH
=> EHLO flan.grepular.com
<= 250-SIZE 52428800
<= 250-8BITMIME
<= 250-ETRN
<= 250-PIPELINING
<= 250-STARTTLS
<= 250-PRDR
<= 250 HELP
=> QUIT
<= 221 glue.grepular.com closing connection
It connects, sends an EHLO, sends a QUIT, and then disconnects.
Here's my exim -bV:
