RFC 3501 の resp-text-code は次のようになっていて atom だけでも OK なはずなのですが、
(snip)
net/imapd.rb の ResponseParser#resp_text_code() は atom の後に SP と TEXT が
å¿…é ˆã«ãªã£ã¦ã—ã¾ã£ã¦ã„ã¦ã€"* OK [CLOSED] Previous mailbox closed." のような応答で
エラーになってしまいます。

実は1.9では修正ずみだったのですが、添付のパッチでどうでしょうか?
問題ないようであれば、ruby_1_8にはバックポートしておきます。
1.8.7については卜部さんの判断におまかせします。
