[Evolution] heelp - evolution receives same mail several times

[Emperor <DarkEmperor gmx net>]

Hi everybody,

since yesterday, I receive every mail sent to me several times... (and
that every 3 min ;) ) I had the same settings for about 1 month and it
went never wrong...

hmm yesterday I ran out of disk space and evoultion complained about it.
perhaps some corrupt files? what should I do?

thx,

nils
