Here is a debug of a typical VM to Email failure:
NV7100#SMTP Response: 220 [OUR SMTP SERVER] ESMTP Exim 4.82 #2 Tue, 14 Oct 2014 21:04:32 +0000
SMTP Response: 220-We do not authorize the use of this system to transport unsolicited,
SMTP Response: 220 and/or bulk e-mail.
To SMTP server: EHLO [OUR PUBLIC IP]
To SMTP server: 22 bytes of data
SMTP Response: 250 [OUR SMTP SERVER] Hello [OUR PUBLIC IP]
SMTP Response: 250-SIZE 52428800
SMTP Response: 250-8BITMIME
SMTP Response: 250-PIPELINING
SMTP Response: 250-AUTH PLAIN LOGIN
SMTP Response: 250-STARTTLS
SMTP Response: 250 HELP
To SMTP server: STARTTLS
To SMTP server: 10 bytes of data
SMTP Response: 220 TLS go ahead
SMTP socket error on write.
At this point, I believe the TLS negotiation is to commence. But we get a socket write error.
This has failed with different SMTP servers, and different ports (225, 465, and 587).
The release notes say that TLS was fixed in R10.11.
Suggestions of what to try next?
