Yes, I saw it after I wrote the mail ...

Ok, that worked well. I tried to deliver some large mails (~50MB) which 
worked well. After sending around 500MB (10 Mails) I opened the mailbox 
with pine over imap. It still took a lot of time (>20s) to open the mbox. 
Indexes should be up2date, so why does it take so long time?

After opening a second time everything is fine.

Any ideas?
