GMail のバギーな IMAP 実装

Opera の lead QA for Opera Mail である Tim が、GMail の IMAP 実装のひどさについて blog で訴えている。

Gmail is by far the quirkiest and most troublesome IMAP implementation I've seen to date. Gmail's own documentation describes how clients must work around the deficiencies built into their implementation. I understand that Gmail's IMAP implementation is still in beta (a Google norm), but some of the basic design choices are at the heart of the problem, which leads me to believe they won't be changing. These decisions are anti-IMAP (even the IMAP spec. author finds Gmail's IMAP disappointing) and cause Opera users headaches.
