I upgraded to 9.100-16 on May 15, 2013 at 12:21am and since then outbound emails originating from either the UTM box (home user license) or the internal network are being held up in SMTP Spool.
According the the SMTP Proxy log:
2013:05:17-11:18:02 myUTMhostname exim-out[2083]: 2013-05-17 11:18:02 1UcfXE-0001yu-4x Remote host smtp.hot.glbdns.microsoft.com [65.55.162.200] closed connection in response to AUTH PLAIN
2013:05:17-11:18:02 myUTMhostname exim-out[2082]: 2013-05-17 11:18:02 1UcfXE-0001yu-4x == myemail@gmail.com R=smarthost_route T=smarthost_smtp defer (-18): Remote host smtp.hot.glbdns.microsoft.com [65.55.162.200] closed connection in response to AUTH PLAIN
I looked at the thread by Firestorm entitled "Inbound mail not being delivered since update to 9.100-16" created yesterday at 3:06am. The post by BALfson to add a host to skip TLS negotiation hosts/nets did not help me (it was a long shot since the errors noted by Firestorm was not the same).
My email on the UTM is setup so that all SMTP traffic is intercepted (Transparent mode) defined in Email Protection: SMTP: Advanced. I defined a smarthost to use smtp.live.com on port 587 set to require authentication with my username and password filled in. I do not have the Management: Notifications: Advanced: External SMTP server status enabled.
This setup has been working in version 9.006.005 and stopped working immediately after 9.100-16 so that not even the UTM could email me letting me know the firmware was applied successfully.
Is this a bug and is there a workaround?
Thank you.
