IMAPS Scanner and Thunderbird 60 Email Client

[dbergst 1]

I just started running Thunderbird version 60 and ran into problems with sending and receiving emails.  Initially I reported these issues with the Thunderbird team but it was soon discovered that the problem might be antivirus or firewall related.  Sure enough, I tried disabling the IMAPS Scanner Setup in EIS and the email client started behaving correctly.  Any thoughts on what I can do to re-enable the IMAPS scanner?

Do you know what IMAP server (vendor, version) is installed on the mail server that you connect to?

Thank you Marcos, the IMAP server is Google (imap.googlemail.com).

No problem here using TBird ver. 60 with AOL client e-mail - IMAPS - on Eset IS 11.2.49. Also, Eset scanning encrypted e-mail w/o issue.

I'm not sure what is different about my setup here; IMAP is connecting over the default port (993), and the ESET software version in 11.2.49.

No problems here either:

I'd suggest contacting Customer care for further troubleshooting.

Thanks, guys.  Per Marco's response I have opened a case with ESET to help resolve this issue.

As it turns out, I discovered that when the IMAPS Scanner was enabled, ESET was blocking all connections over port 993.  After running a repair on the ESET software installation, the port is no longer blocked and my Thunderbird 60 client works as expected.
