Spamfilter 4.7.4.246 registered listening on port 25
Exchange 2016 CU9 on WinServer 2012r2 listening on port 2551 Spamfilter.ini EnableTLSSupport=1 If I disable TLS 1.0 and enable TLS1.1 or TLS1.2 only for Exchange I get Socket Error 10053 when spamfilter sends the email to exchange. Below is sample from the logfile with TLS 1.2 only enabled for exchange when sending email from my personal yahoo.com account to my domain.com account. With TLS 1.1 or 1.2 enabled I can telnet to exchange and send an email to my domain.com account. I need to enable only TLS 1.2 on exchange. 07/09/18 20:27:00:820 -- (41059152) Detected TCP Connection: 74.6.135.125 on port: 25 07/09/18 20:27:00:820 -- (41059152) Connection from: 74.6.135.125 - Originating country : United States 07/09/18 20:27:00:898 -- (41059152) Received MAIL FROM: external@yahoo.com 07/09/18 20:27:00:929 -- (41059152) Received RCPT TO: internal@domain.com 07/09/18 20:27:00:961 -- (41059152) Resolving 74.6.135.125 - sonic310-15.consmr.mail.bf2.yahoo.com 07/09/18 20:27:01:367 -- (41059152) Mail from: external@yahoo.com 07/09/18 20:27:01:633 -- (41059152) - MAPS search done... 07/09/18 20:27:01:633 -- (41059152) RCPT TO: internal@domain.com accepted 07/09/18 20:27:01:711 -- (41059152) From header (external@yahoo.com) matches MAIL FROM (external@yahoo.com) 07/09/18 20:27:01:727 -- (41059152) Email Subject: Re: test in 07/09/18 20:27:01:727 -- (41059152) Start CheckWL_Keywords 07/09/18 20:27:01:727 -- (41059152) End CheckWL_Keywords 07/09/18 20:27:01:727 -- (41059152) Checking SFDC 07/09/18 20:27:01:914 -- (41059152) Checking SFDE 07/09/18 20:27:02:180 -- (41059152) Checking SF0Day 07/09/18 20:27:02:180 -- (41059152) Start CheckBL_Keywords 07/09/18 20:27:02:211 -- (41059152) End CheckBL_Keywords 07/09/18 20:27:02:211 -- (41059152) EMail from external@yahoo.com to internal@domain.com passes Bayesian filter - 0% spam (0ms) 07/09/18 20:27:02:211 -- (41059152) Checking SURBL 07/09/18 20:27:02:211 -- (41059152) Checking URLs in emails against MAPS 07/09/18 20:27:02:211 -- (41059152) - URLs In MAPS search done... 07/09/18 20:27:02:258 -- (41059152) Starting queueing procedures 07/09/18 20:27:02:274 -- (41059152) EMail from external@yahoo.com to internal@domain.com was queued (Indy239EB798-02A6-4137-9CC4-618D9CF10383.~tmp).

Hi mmmctune, We had recently found a bug likely causing the issue you are experiencing. This was resolved in the latest SpamFilter v4.7.4.250 - can you please try upgrading to see if that was the cause? // New to VersionNumber = '4.7.4.250'; {TODO -cFix : Outbound TLS connections were only being made with TLS 1.0, even if TLS 1.1 and TLS 1.2 were configured and in use correctly for inbound emails} |
