Issue/Introduction

Significant increase in "abort message" actions following an upgrade from SMG version 10.6.6 to SMG version 10.7.x

 

Cause

A large number of SMTP session timeouts are seen - 

2021 Jul 11 16:58:35 +08 (info) ecelerity: [8302] [info]: SMS_AUDITLOGGER-01493: SMTP session aborted.
2021 Jul 11 16:58:35 +08 (err) ecelerity: [8302] [error]: SMS_AUDITLOGGER-02127: Unhandled rejection phase 15
2021 Jul 11 16:58:35 +08 (err) ecelerity: [8302] [error]: SMS_AUDITLOGGER-02136: Error handling rejection event.
2021 Jul 11 16:58:35 +08 (info) ecelerity: [8302] ML-REJECT: Rejection on: 192.168.0.231:25, sent to host: 209.85.218.47:44868, Audit ID c0a800e7-493ff7000000206e-d9-60eab18e45aa, 421 4.4.2 service timed out.#015

The OpenSSL library used to secure TLS connections has changed significantly between 10.6.6 and 10.7.x which is why we are seeing the difference in the nature of MTA in processing the messages. 

Environment

Product Name : SMG

The Issue is witnessed in SMG version 10.7.x 

Resolution

This is currently being investigated and would be fixed in SMG version 10.7.6. This article will be updated once the issue is fixed.
