Hi, Toni

 

So, that message indicates that SmarterMail can't load the message from the .grp. Either the .grp is corrupt or your AV/Anti-malware scanner deleted the .grp or a specific message inside the .grp. (Though, generally, if AV detects a virus it will delete the entire .grp..so corruption is probably the issue.)

 

Make sure you have exclusions in place for C:\SmarterMail\Domains -- or whatever path you're using for the domains folder -- within your AV/AM software. That would remove those services as the cause. This includes making sure Windows Defender has the same exclusion, if it's not in place already.

 

If you're not running AV/AM, then the .grp was definitely corrupted somehow. So..no, it's not a security issue. 

Dear Sir

we also encounter this issue before upgrade to SmarterMail Enterprise Edition

A message has been removed from this mailbox by an entity other than this

This message is a replacement for the missing message.
 

From Dominic

This type of message only occurs if there is an error feeding the message headers or body from the group file during a POP session. As Derek Curtis responded above, this usually indicates that the grp file is corrupt or a 3rd party app removed or modified the grp file.

Hi,

I have similar issue today with one of customer getting below message, at the same time i have verified that AV scanned is excluding required dirs of SM including mail storage path, spool, setup folder

 

A message has been removed from this mailbox by an entity other than this
program, probably by a virus scanner.

What can be other cause of getting above message

 

Thanks

 

 

Same here - just started happening after upgraded this past weekend to version 15.7.6663

No antivirus on server.

We have same problem with exact message

 

 

we use kaspersky internet security 2018 and in the report log of KIS2018 there is no log about removed message in email (outlook 2016) at that time .  even after disable and remove antivirus (kis2018/windows defender ) temporally , still randomly we get (Message removed) .

FYI only two user struggling with that issue ,,, we use shared host server and we don't have access to smartmail server (SmarterMail Enterprise EditionVersion: 16.3.6585) 
so after call our host support company they have't any idea why this happen.!

anyway base on @derek-curtisi said about corrupted .GRP file , what we can do to solve this weird issue ?

 

to answer your answer with a picture
every day all mail in one grp file

every folder is a folder containing grp files
