■ [Debian] clamav-daemonのUNIXソケット名が変わっいた

Mar 19 12:00:05 localhost sm-mta[23583]: p2J305Q4023583: Milter (clamav): local
socket name /var/run/clamav/clamav-milter.ctl unsafe

というのが連打されてしまっていた。

clamav-milter installs an m4 macro in /etc/mail/m4/clamav-milter.m4

The installation documentation says to include this macro in your sendmail.mc file.

Doing so will result in clamav-milter not working, with errors for each incoming email, as follows:

Milter (clamav): local socket name /var/run/clamav/clamav-milter.ctl unsafe

Milter (clamav): to error state

This happens because the clamav-milter.m4 macro has the following line:

INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav/clamav-milter.ctl, F=, T=S:4m;R:4m')dnl

That line points to a non-existent socket. The actual socket name is, instead, 'milter.ctl'.

The bug is fixed by changing the clamav-milter.m4 line to read instead:

INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav/milter.ctl, F=, T=S:4m;R:4m')dnl

Sorry, I've been meaning to report this for a long time - just getting tired of always having to correct it... ;)

というのが有ったので、おうちのパッケージのバージョン0.97+dfsg-2では少し違うようなので、とりあえず

としてエラーをでなくした。(正しい修正か不明)
