Очень удобно. Специально провёл тест: отослал 2 письма на gmail с одинаковым Subject, но не в ответ одно на другое, а независимые письма. Через Web-интерфейс Гугль их дебильным образом показывает в одном треде. Очень хорошо суть вопроса изложена в листе рассылки mplayer, http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2007-June/009369.html The message subject has nothing to do with threading, although some mail readers will automatically place messages with the same subject under the same top-level thread. Threading, on a per-message level (that is, to determine which message is the "parent" of a new message in the cascading tree), is done by the In-Reply-To mail header which is set by any good mail client. There are a sizable number of message headers in every E-mail message, providing mostly-technical information which you never see if you don't go looking for it. I believe Gmail provides a way to view those headers, but I have no idea what it is, since I avoid Gmail both for practical (or formerly practical) and for philosophical reasons. The In-Reply-To header in particular gives the exact (and, by and large, unique) numeric ID of the message to which the new one is a reply. Threading is performed on the basis of these headers. The Subject line is completely ignored (other than perhaps as a fallback) except by asocial mail clients, and would not be enough to produce proper message-by-message threading in any case. В последней фразе, между прочим, очень удачное определение "умных" почтовых клиентов (asocial mail clients). -- С уважением, А.В.Коротков, mailto:[EMAIL PROTECTED] -- ubuntu-ru mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-ru
