Cyrus and PHP imap_mail_move

[Marten Lehmann]

Hello,

I noticed, that imap_mail_move() does not move the message(s) on our 
cyrus-imapd-2.2.12-8.1.RHEL4, while imap_mail_copy() works fine. When 
I'm requesting the capabilities, then cyrusd announces NO_ATOMIC_RENAME. 
  Does this mean, that it is not possible to move a message from one 
folder to another directly? Of course one could copy and delete+expunge 
later, but thats annoying and error-prone.

Regards
Marten
