Hi Guys,

Our Pmail (4.70) is working fine together with Mercury (4.8). Only one (1) instance of Pmail is installed at a server drive and will be started by each user. So far so good.

Today one of my users received different complete empty mails. Its inbox was showing an "unknown" sender, subject: "(none)", size: "0.0k". The mail contained nothing, neither plain text not html text. Also the raw view showed nothing - only an empty window. The property window for one of those mails showed a file name (*.cnm) but no property box were checked.

At the server I was able to found the cnm file within the user's mailbox. But it was empty, too. Mercury didn't receive anything from outside for that user during the affected time.

I have checked the single mailbox folders in user's Pmail and found inconsistencies which I could repair by re-indicating the folder. Now all seems to be ok.

I know that that user often doesn't shutdown its computer in the evening properly, but is using an energy saving sleeping mode of W7 instead. That could cause that the mailbox is not properly closed at the server.

Has anybody an idea what caused to those empty messages?

Cheers

Joerg

Hi Joerg,

There was a post back in 2008 that David Harris responded.  Unfortunately he did not provide an explanation for what causes these messages.

Is your Pegasus Mail gateway configured to force all mail through Mercury?  I'm just thinking out loud wondering whether the message originated locally but is not visible in Mercury because local mail is not forced through.

Hi Brian, good morning greetings across the water,

Yes, Pmail is configured to force all mail through Mercury, also local mail traffic. But the core module showed nothing. I have also read David's post from 2008 but didn't find any 'read only' cnm files in user's inbox directory. But the behaviour was the same - deleting of such an message caused to a new one. For the moment, after re-indicating the folder, the problem is gone. I will observe it.

Regards

Joerg

Such messages might get created by my PGP and S/MIME add-ons if cancelling at send. These messages will stay in the message queue until the next SMTP delivery at which time the should be deleted (I have no idea what happens if Mercury is involved, though). If the PGP or S/MIME add-ons aren't involved at any point there must be another reason, though.
