#下面log 抓不到IP         (dovecot.log檔)

Jan 04 17:40:55 auth: Info: ldap(root@mydomain,45.63.34.194): unknown user
Jan 05 20:07:04 auth: Info: ldap(root@mydomain,98.158.177.98): unknown user

Jan 05 20:12:40 auth: Info: ldap(postmaster@mydomain,98.158.177.98): invalid credentials

grep '45.63.34.194' dovecot.log|wc -l
110
grep '98.158.177.98' dovecot.log|wc -l
1648

dovecot.iredmail.conf 或預設安裝的 dovecot.conf 皆無法抓到以上兩IP

現使用dovecot.iredmail.conf 
最後兩行合併為一行:
         ^%(__prefix_line)s(auth|auth-worker\(\d+\)): (pam|passwd-file)\(\S+,<HOST>\): unknown user\s*$
            ^%(__prefix_line)s(auth|auth-worker\(\d+\)): Info: ldap\(\S*,<HOST>,\S*\): invalid credentials\s*$

           #改為
            (pam|passwd-file|dap)\(\S*,<HOST>(\)|\S*\)): (invalid credentials|unknown user|Login attempt with empty password)\s*$.

是可抓到;
不知版主有何其他看法意見.

Thanks.

iRedadmin-Pro 要釋放隔離信件 , 剛開始無法做到, 隔幾分鐘後再做釋放 ,則可以.

何以會這樣? 附檔為log 檔.(已寄出)

1).14:00 剛開始登入做 release 動作(全選), 網頁不動 ,最後出現 通知"postmaster@" 的訊息 ; 應是timeout 造成

2).14:16 再重新做release 1封 , 再2封 ;再全選 , 皆可釋放.

另有安裝:mod_security , 對區網有開放權限.

Thanks.
