IFW Email send failure 96 - Socket Error 0x273F
Posted: Mon Oct 21, 2019 3:08 pm
I have purchased IFW a few months ago and am trying to get to know it. I however have a problem with sending emails. On 4 different machines I get the same “Email send failure 96 - Socket Error 0x273F” error when trying to send a test-mail.
I do not understand anything about socket tracing. It happens with a non-secure connection (port 25) and a TLS connection (port 587).
It happens on 2 Win7 x86 machines, which both use the Windows Firewall. The 2 other machines are Win7 x64 and use Norton Security. It does not matter whether the firewall is switched off or not. All machines have IFW v3.33.
When I boot from a TBWinRE CD I also get the same error message, although I do not know whether it is supposed to work in TBWinRE. It has an internet connection, because it can search for an update for IFW.
