光明<\/a>をたどったんですが，芳しくありませんでした．IPv6+SSLのパッチが当たったというRedhat系のrpmのソースをいろいろいじっていましたが，IMAP部分だけではbuildできません1<\/a><\/sup>また，RPM系はどういうわけか，shared libraryにこだわっていて，関連ライブラリーなどをsharedとしてインストールしなければなりません．はまり始めると，底なしの依存性地獄に陥るでしょう^^;<\/span>．<\/p>\n

そこで，Slackwareに戻って，Slackware-currentにあるalpine-2.20について，コマンドを受け取るルーチンに，受け取ったコマンドをログに書き出すように細工して確認したところ，IPv6だと，文字化けして受け取っています2<\/a><\/sup>slurpというサブルーチン．<\/span>．たとえば，こんな感じです．<\/p>\n

Feb 28 12:43:54 je1sgh imapd[1807]: Slurp input (dump): ^V^C^A^B<\/pre>\n
ですが，それが解っても，これ以上はどうしようもありません．<\/p>\n
一つ腑に落ちないのが，Slackwareで使用している，alpine-2.20というソースの出所が見つからないのです．UW IMAPを引き継いだPanda IMAPとかいうプロジェクトらしいんですが．<\/p>\n
もうあきらめようと思って，ダメ元でUW IMAPのサイト<\/a>にある，alpine.tar.bz2をbuildしてみました．展開すると，alpine-2.00というディレクトリーに展開されます．バージョン番号から，Slackwareのものよりずいぶん前のものと推測され，期待薄です．<\/p>\n
ところが，buildしてimapdだけコピーしてみると，なんと，全く問題なくIPv4, IPv6のどちらの接続も受け付けます．<\/p>\n
なんだったんでしょう^^;<\/p>\n
\"imap-ssl-ipv6\"<\/p>\n
少なくとも，Slackware-14.1, -currentのIMAPサーバーはぶっ壊れています．<\/p>\n
追記<\/h2>\n
その後の調べで，Alpine 2.20のソースでもOKです．パッチを当てずにオーソドックス3<\/a><\/sup>configureのオプション，makeのオプションは，はalpine.Slackbuildを参照．<\/span>にbuildしてできたimapdを\/usr\/sbinに置けばちゃんと動きます．<\/p>\n
しかし，どうしたわけか，alpine.Slackbuildでbuildすると，だめです．alpine.Slackbuildも，imapdにはパッチを当ててないんですが．<\/p>\n
また，上記のalpine-2.00もalpine.Slackbuildでbuildすると，IPv6を受け付けなくなります．<\/p>\n
できれば，原因を解明して，Slackwareの開発者にフィードバックしたいのですが，全く解りません^^;<\/p>\n
解決<\/h2>\n
Slackwareの問題点解りました．<\/a>ただし，開発者への連絡法が解りません^^;<\/p>\n","protected":false},"excerpt":{"rendered":"
