[postfix-jp: 3349] SASLの動作確認

[Norihiko Yoshida <nori@xxxxxxxx>]

吉田と申します。
「3339: SASLの動作確認について」と似た質問をさせて下さい。
やはり dovecot (pop3s) の SASL で smtp-auth しようとしています。

http://www.postfix.org/SASL_README.html#server_dovecot
http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL

上記あたりを見ながら設定したのですが、
EHLO で「250-STARTTLS」の次くらいに表示されるはずの
「250-AUTH PLAIN LOGIN」の行が表示されず、認証してもらえません。

探しかたが悪いのかも知れませんが、ウェブで同様の事例は
見当たりませんでした。チェックは重ねたつもりですが、
何かお判りのかたはいらっしゃいますでしょうか。
どうかよろしくお願い致します。
