[Dovecot] dovecot-1.2.9: OK No messages copied

[Attila Sipos]

I can understand that if using a set of UIDS or a UID range it would be complicated to return a fully-descriptive result and from what I can see, the IMAP RFC author was trying to avoid this complexity.

However, it someone specifies JUST ONE UID and that UID is non-existent, then a NO response could be a more useful response.  I know the spec allows a response of OK but it is possible that this was not the intention for a single non-existent UID.

Regards

Attila

Dovecot's behavior is correct. This (or things related to this) has been discussed in IMAP protocol mailing list. Basically it's not an error to use nonexistent UIDs. If you want details, ask in IMAP protocol ml and someone will probably explain.
