郵件伺服器查找主機名速度慢
您好,我的郵件伺服器接受 SMTP 連接的速度很慢。
我找到了一個教程,可以在我的 Exim4 中停下來,然後執行下面的命令來查看它的位置。
exim -bd -d -oX 587
沿著出口走,哪裡有更多的停機時間。你能幫我弄清楚為什麼它這麼慢。
29136 Connection request from 187.23.45.188 port 61995 29136 search_tidyup called 29136 1 SMTP accept process running 29136 Listening... 29141 sender_fullhost = [187.23.45.188] 29141 sender_rcvhost = [187.23.45.188] 29141 Process 29141 is handling incoming connection from [187.23.45.188] 29141 host in host_lookup? yes (matched "*") 29141 looking up host name for 187.23.45.188 -----> VERY SLOW HERE
我解決了這個問題。
我編輯了一個文件
/etc/exim4/exim4.conf.template
並修改了這行:#host_lookup = * rfc1413_hosts = * rfc1413_query_timeout = 0s
