[Dovecot] Wrong file accessed after file was renamed because of wrong size

[Rolf Eike Beer]

I'm migrating from Courier-IMAP. On first access of folders I get this log
(slightly anonymized):

Jan  1 18:38:27 mail dovecot: imap(username): Error: Cached message size smaller than expected (1452 < 1668)
Jan  1 18:38:27 mail dovecot: imap(username): Error: Maildir filename has wrong S value, renamed the file from /var/vpopmail/domains/domain/username/.maildir/cur/1206559119.14350.mail,S=1452:2,RS to /var/vpopmail/domains/domain/username/.maildir/cur/1206559119.14350.mail,S=1668:2,RS

This is the same in 2.2.6 and 2.2.10.

Greetings,
