@Arron, When switching to port 143 and STARTTLS, connection errors no longer occur in the above application. However, they continue to be recorded in the Windows log, most likely from other clients...

Version 23.5.3 I tryed to reproduce the issue but in all rules I set "run program" this works now! I can't understand why or what I did but now it works. This is cfilter.ini: [SpamFilter]AutoWh...

Thanks, I will test and let you know. On another note, I made two support requests on the website for this issue and received no reply. Very disappointing.

I have the Domain in my Allowlist, yet still get the SPF failure.

No problem. It'll likely be Tuesday before I respond, we are closed Monday for our Memorial Day.  Enjoy your weekend.

Can you wait till monday? Now I'm not at work.

I wasn't able to reproduce an issue with any of the actions causing the "run program" action to not actually be executed in MDaemon 24.0.0.  What version are you using? Can you post the actua...

If the FROM HEADER contains ... ...then copy this message to ... (I've removed this line) and run program C:\WINDOWS\system32\mstsc.exe

How do you know the program is not starting?   Are there any errors in MDaemon's system log? Are there any errors in the Windows Event log? Does the user that the MDaemon service is ru...

If I set a rule with "run program" this is executed in background or in the log I try "Process executed" but the program doesn't start.

Thank you for the dump files.  I've submitted a bug for the development team to take a look at. 

If you change it to use port 143 and STARTTLS, do you have the same issue?   If you leave the port set to 143 and turn off the encryption, do you have the same issue?  Once the test...

@Arron Are you using the dedicated IMAP SSL Port, 993, or the standard IMAP port 143? Port 993 is used. Are there any other ideas to solve this problem?

There are."RA v24 Dumps.zip" archive with 5 dump files uploaded.

Are there dump files being created in the MDaemon\Dumps directory?  If there are, can you upload them to us at https://mdaemon.sharefile.com/r-rc3922c1eed334d4dbf5e34f0bd04ccd6
