Hi,

These are created by the University of Washington's implementation of an IMAP server. Notice the date is nearly 2 years ago. At some point, it seems your site was running imap-uw.

nope, i dont think so. i created completly new mailbox and mailed to it from extern. after deleting this mail using pop3-client same text was left in mbox but with current date. it must be dovecot related. we use dovecot from 1.0rc7 to 1.0.15 and never a case like this occured. also this machine had a lot of updates. now, by updating from 1.0.x (most 13) to 1.1.1 some users have this problem of retrieving ~1000 - ~2000 Mails with this internal message. The messages are from one to other moment in mbox, there is no delivering by postfix etc. this is completely new to me. Hmm.... If users asking i say it is a one time incident, but i do not really know...

Thanks Andre
