sync stops after exactly 102 mails

[Timo]

hi,

i am using offlineimap on my synology nas for backup my gmx account. its all working exept tha the sync just stops always after 102 mail. if i kill the python process and start over, the next 102 mails are synced before it hangs again.

in the imap debug log i can see the following message when offlineimap is in the hanging state:

---
imap.gmx.net handler:
 [imap]:   58:45.32 imap.gmx.net handler UID:HPAG109.ready.set
imap.gmx.net reader:
 [imap]:   59:15.33 imap.gmx.net reader poll => []
 [imap]:   59:45.36 imap.gmx.net reader poll => []
 [imap]:   00:15.39 imap.gmx.net reader poll => []
 [imap]:   00:45.41 imap.gmx.net reader poll => []
 [imap]:   01:15.44 imap.gmx.net reader poll => []
 [imap]:   01:45.46 imap.gmx.net reader poll => []
---

what could be the reason for that?

regards
timo
