徒然なるままII

日記帳までこまめに更新しませんが、思ったことを書き残していきます。

愚痴

まぁ、こういう時代だから致し方ない、と言ってしまえばそれまで。
んなことは理解しているつもり。

同一メールを複数端末のMUAで読み出す手順、それもPCベンダFAQサイトの
一コンテンツとして公開するのに、POPでの手順を案内するかな、普通。

担当者曰く
「OSの操作手順ですから」
ですと。
はぁ、OSがthe internetの規定処理に準じているとでも思ってるのかしらん。

POP, SMTP, IMAPそれぞれ、どんなプロトコルでMTA - MUA間ではどのような処理が行われるべきなのか、を踏まえてほしい。今のISP側でPOP処理でのメールボックス サイズが大きくなっていかない理由だって、ちゃんとRFC 1939(POP version 3)に明記してあるのに。
いちPCベンダであれば、the internetがinfrastructureになり、PCがcommodity化した現在だからこそ、きちんと啓蒙すべき立場なのだから。その話を担当者にしたら
「それは社のポリシですか?」

....だったら、もうtechnical reviewerから俺を外してほしい。

そりゃ業務で作成しているのでしょうが、そもそもFAQコンテンツって、
ユーザのために作成し、サポートコストを低減する目的があるんじゃないの?!


>8. Scaling and Operational Considerations

>   Since some of the optional features described above were added to the
>   POP3 protocol, experience has accumulated in using them in large-
>   scale commercial post office operations where most of the users are
>   unrelated to each other.  In these situations and others, users and
>   vendors of POP3 clients have discovered that the combination of using
>   the UIDL command and not issuing the DELE command can provide a weak
>   version of the "maildrop as semi-permanent repository" functionality
>   normally associated with IMAP.  Of course the other capabilities of
>   IMAP, such as polling an existing connection for newly arrived
>   messages and supporting multiple folders on the server, are not
>   present in POP3.
>
>   When these facilities are used in this way by casual users, there has
>   been a tendency for already-read messages to accumulate on the server
>   without bound.  This is clearly an undesirable behavior pattern from
>   the standpoint of the server operator.  This situation is aggravated
>   by the fact that the limited capabilities of the POP3 do not permit
>   efficient handling of maildrops which have hundreds or thousands of
>   messages.
>
>   Consequently, it is recommended that operators of large-scale multi-
>   user servers, especially ones in which the user's only access to the
>   maildrop is via POP3, consider such options as:
>
>   *  Imposing a per-user maildrop storage quota or the like.
>
>      A disadvantage to this option is that accumulation of messages may
>      result in the user's inability to receive new ones into the
>      maildrop.  Sites which choose this option should be sure to inform
>      users of impending or current exhaustion of quota, perhaps by
>      inserting an appropriate message into the user's maildrop.
>
>   *  Enforce a site policy regarding mail retention on the server.
>
>      Sites are free to establish local policy regarding the storage and
>      retention of messages on the server, both read and unread.  For
>      example, a site might delete unread messages from the server after
>      60 days and delete read messages after 7 days.  Such message
>      deletions are outside the scope of the POP3 protocol and are not
>      considered a protocol violation.
