Description

FortiMail units may sometimes write log messages similar to the following:

2008-01-10 15:07:54 log_id=0501080300 type=spam subtype=detected> pri=information session_id="" from="" to="" msg="SocketSmtp receive banner> from 1.1.73.66 failed SocketException( 115 ) , Socket.cpp:573, "Operation now in progress""

Components
  • FortiMail 2.8 and greater
ExplanationThis socket exception occurred during recipient verification with the protected email server through SMTP. The recipient verification process didn't finish. This is most likely caused by the sudden session termination by the protected  email server. When this exception occurs, the recipient verification process would not finish, and therefore message delivery would temporarily fail. The sending mail transfer agent (MTA) will retry to deliver the email.
