EBM always crashing


I have a problem of EBM always crashing.
Initially, I thought it may have something to do with it dredging DIRECTLY from Max OS X Mail application.
If I have a mailbox with a lot of bounces (say, 2,000 or more), the application WILL (not MAY) crash.

So, I though I'll get EBM to dredge DIRECTLY from my Mail Server.
But, it still crashes! Very frustrating!

Any ideas what's wrong?

Find below the crash report fro OS X.

I experience similar problem.

When I have to process a mailbox with large number of bounces - after 10-12 minutes of work the application crashes (always). Tried with Antivirus ON and OFF - the crash always happens.

Today I discovered that it only happens when the application communicates with the "List Manager Script". When the "LMS" is deactivated from the "Preferences" windows - the application works fine.
So at least in mine case - the problem is somehow related to the "LMS".

Working Environment: Windows 8.1 (64 Bit)

Ok, our script name is MLM actually :)
If you use MLM perhaps you need to set eMail Bounce Handler to work at a slower pace.


Staff member
Look at the two 'connection' fields. You can set the frequency of the mailbox checking and the number of messages to process on each session.


New Member
Thank you for the suggestion!
I have experimented many configurations (see the attached screen-shot).
The problem is that the EBM does not stop (and disconnect) after the bounces/connection limit is reached.
It simply updates the server (deletes the processed messages) and continues checking the rest of the mailbox.

I have expemented this on a number of computers running Windows XP, Windows 7, 8 and 8.1
The result is always the same - the application just refreshes the mail server (deletes the processed messaes) and goes ahead checking the rest of the messages.
Over the time the process starts to use more RAM (>100 Mb) and finally crashes.
I think it crashes faster if the application is send to the windows background - when the application window is on the foreground - it takes longer before the crash.

Are you running an anti-virus? Have you tried to deactivate the past that check incoming emails?


New Member
Hello Stan,

The bounce handler crashes, and it does so before I could have saved a copy of the bounced emails.

How can I get the previous unsaved version to come back? I don't have a copy of the emails that bounced back, and some of them were suspected honeypots :-/


New Member
I just purchased the whole package (4 products), I am running it on macbook pro with latest OS updates.

Whenever there are more than 2000 messages it keep son crashing. have been trying everything but it does not work.

If it works perfectly on windows I will use it on windows, Please suggest.

Thanks in advance for the help.

When does it crash? in front of your eyes? I mean eMail Bounce Handler can crash if your computer goes in sleep mode for example.


Screenshot 2020-02-10 at 10.15.43.pngHi I am having this issue too.
The Bounce handler goes into a spnning wheel of hell situation when starting the "Deleting message from IMAP server" process and eventually crashes.
