repeat messages

[skiv71]

hi,

i been running a zimbra server for several years now... think i started with 5.x

currently running 7.x (not sure which) but since upgrading to v6 last year or so... i've an annoying problem.

zimbra somehow is receiving identical copies of messages dated months ago.

so clients are ending up with new messages that are post dated so dont appear at the top and they have to trapse through trying to find that.

to put things into perspective...

i've currently got to trawl a folder with 700 messages that are post dated.

its getting really annoying.

anyone?

nothings changed in my config during migration from 5-7 and it never ever used to be an issue

please help :-/

Neil
