GMail作為Ubuntu Linux的SMTP主機

終於找到此作者blog有詳細的介紹,不用自己架mail server,用Gmail來幫忙發信


dpkg-reconfigure exim4-config

出現設定畫面後，開始如下步驟完成設定：

1.選擇「mail sent by smarthost; received via SMTP or fetchmail」

2.輸入伺服器的網域名稱:gmail.com

3.接著「listen on for incoming SMTP connections」設定為127.0.0.1 (僅允許本地端連線)

4.將「Other destinations for which mail is accepted」設定保留空白

5.將「Machines to relay mail for」設定保留空白

6.將「Machine handling outgoing mail for this host (smarthost)」設定為smtp.gmail.com::587 (重要)

7.「hide local mail name in outgoing mail」選擇No

8.「don’t keep number of DNS-queries minimal (Dial-on-Demand)」選擇No

9.選擇「mbox」

10.「split configuration into small files」選擇No

11.接下來，編輯 /etc/exim4/passwd.client 加入帳號及密碼設定，格式如下。

*:username:password(你自己的gmail帳密)

確定exim4服務是否啟動 netstat -tlnup
若無則 /etc/init.d/exim4 start 

wordpress MU用gmail發註冊認證信

1.修改var/www/wordpress/wp-includes/pluggable.php
  將$phpmailer->IsMail(); 改為 $phpmailer->IsSMTP();

2.修改var/www/wordpress/wp-includes/class-phpmailer.php
