これは、このディレクトリの権限の問題のようです:
/var/spool/amavisd/tmp/
ログメッセージに基づいて、ユーザーamavis
はこのディレクトリにアクセスできないようです。
あなたが述べたコメントとして、RPMForgeは機能しますが、RPMForgeはEPELと同じ標準に準拠していないため、必ずしも問題を修正する適切な方法ではありません。
EPELの問題は、「clam」ユーザーがamavisフォルダーにアクセスできないことです。これをEPELで動作させるのはかなり簡単です。
usermod -a -G amavis clam
chmod g+rx /var/spool/amavisd/tmp
この広告はamavisグループを要求し、次にamavisグループにtmpディレクトリへのアクセスを許可します。
