Rsync error

[link7722]

Hello
I am trying to copy a directory using rsync:

rsync -ar /sourcedir /destinationdir

The directory is containing mail files (in maildir format).
I get the following error:
rsync: rename "/FilsrvBackup/maildata/username/Maildir/cur/.1349439381.V6802Ib16054M788390.mail:2,S.pmUCx6" -> "username/Maildir/cur/1349439381.V6802Ib16054M788390.mail:2,S": Invalid argument (22)
For every single mail (which is a single file) i get the above error.
As shown in the error, the original file has the name "1349439381.V6802Ib16054M788390.mail:2,S" and it seems that it tries to rename it to "1349439381.V6802Ib16054M788390.mail:2,S.pmUCx6".
Any help would be appreciated.
Thank you

Dear link7722,

I readily admit I do not know what this error message really means. But have you tried the --dry-run option ? Maybe this gives you some extra clue.
