Exim4 的問題 (refused:too many connections)

[ycliao]

我的機器裝 Sarge 跑 Exim4 當 Mail Service
最近不知為什麼兩三天 就會無法收信也無法寄信
檢查 /var/log/exim4/mainlog 發現最後面都是這種訊息

我用google查過有人說是要設定以下參數

代碼: 選擇全部

smtp_accept_keepalive       = true
    smtp_accept_max             = 320
    smtp_accept_max_per_host    = 16
    smtp_accept_queue           = 128
    smtp_accept_reserve         = 20
    smtp_connect_backlog        = 16
    smtp_check_spool_space      = true
    smtp_receive_timeout        = 18m


但是是要加在哪個檔裡面呢?

補充說明一下
收信是完全收不到,寄信的話
在 server 上面是可以寄信到外面
但是如果用outlook來寄信就不行,錯誤訊息是
'421 Too many concurrent SMTP connections; please try again later'

[kibymo]

可以cat 一下/etc/exim4/update-exim4.conf.conf嗎?

dc_other_hostnames="這裡輸入domainname試試"

也可用dpkg-reconfigure exim4-config 修改

[ycliao]

以下是 /etc/exim4/update-exim4.conf.conf的內容

dc_eximconfig_configtype='internet'
dc_other_hostnames=''
dc_local_interfaces=''
dc_readhost=''
dc_relay_domains='140.112.41.*:m8.ntu.edu.tw:140.112.231.195:tl.ntu.edu.tw:61.66

dc_minimaldns='false'
dc_relay_nets='140.112.41.0/24:140.112.231.195:140.112.253.138:61.66.162.58:220.
132.58.96'
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname=''


請問加入domain name的意思是像
"abc.ee.ntu.edu.tw"
這樣嗎?

[kibymo]

若你的mail 是001@abc.ee.ntu.edu.tw
就填入abc.ee.ntu.edu.tw試試
我也不知那是什麼意思,有加就收的到,拿掉就不行
祝成功

[ycliao]

還是不行耶, 我填入domain之後還是有出現下面的log

2005-05-28 23:28:43 End queue run: pid=20683

2005-05-28 23:55:33 Start queue run: pid=20819


雖然不會一直掛掉, 但是會一段一段的
從"End queue"開始掛掉,到"Start queue"才又可以
有別的方法嗎?

[ycliao]

跟大家報告一下,
後來我把第一篇裡面的參數加到
/etc/exim4/update-exim4.conf.conf
裡面,就ok囉...
