I have automated SQL Server 2005 reports that are being emailed on a regular basis. They stopped working after purchasing and using the McAfee service. No bounce back message, just customer's complaining that they were no longer receiving their reports.

The report server is not giving any errors. They are being marked as successful. However my server logs are giving me the following error for every email I try to send through reporting services:

vent Type: Warning
Event Source: smtpsvc
Event Category: None
Event ID: 4007
Date: 12/30/2013
Time: 7:31:04 PM
User: N/A
Computer: DELLPE2950-APP
Description:
Message delivery to the host '208.65.144.2' failed while delivering to the remote domain 'mydomain.com' for the following reason: The remote SMTP service rejected AUTH negotiation.
The SMTP verb which caused the error is 'AUTH'. The response from the remote server is '250-p02c11m002.mxlogic.net
250-SIZE 0
250-STARTTLS
250-SUBMITTER
250-8BITMIME
250 PIPELINING

The McAfee control panel is hosted on the mxlogic.net server. So that is why I am assuming it is an issue with the McAfee service.

I turned off the McAfee service this yesterday. That did not seem to help. Then I restarted my servers this morning and that helped. I was able to send the reports. However, I realize that the issue could still be McAfee because it could just be a timing issue in how McAfee proliferates. I've since turned the McAfee service back on and sent more reports successfully. No SMTP errors in the event log yet. But again it could be a timing issue. Or perhaps I just needed a server restart.

Anyone else encounter a similar issue with the McAfee service? If so, how did you resolve it?
