External account polling, message copying

[virtualmarc]

Hello Zimbra Forum Users, Mods and Administrators,

I'm polling E-Mails from an external POP Account.
But I often get Error messages like this one:

system failure: Unable to add incoming message, /opt/zimbra/store/incoming/1310755995127-841.msg does not exist.

The Folder has writing permission for all users and other external mail accounts write into it.

Has anyone an idea how to fix it?

Regards,
Marc Vollmer

How to fix what? The error is telling you that the incoming message doesn't exist, how can Zimbra download an non-existent message?

On the external Mailserver all Mails are available.
It's not only this file.
I'm getting this message on every login and every minute.
The Mail account has over 22000 E-Mails ans nearly every of them got downloaded without problems.

On my last Zimbra Server (moved to another Server, complete reinstallation, no migration) I didn't get this problem.

Edit:
My old Zimbra Server is also polling this mail account without any problems.
No E-Mails get deleted.
