(3) system email name, at will; (I wrote admin@ip here)

(4) the IP address of the inbound SMTP connection to be monitored:

127.0.0.1 (in this way, only the native machine can take advantage of exim4)

* (everyone can use it)

192.168.0.0 IP 24, which is available only for this range

(5) other acceptable destination addresses: (empty)

(6) Mail forwarding for these hosts: (empty)

(7) do you keep DNS queries to a minimum (dial Dial-on-Demand on demand)? No

Method 2: use smarthost to send messages

(1) split the configuration document into small files? No

(2) Select "send mail using smarthost; no local mail"

(3) system email name, at will; (I wrote admin@ip here)

(4) the IP address of the inbound SMTP connection to be monitored:

(5) other acceptable destination addresses: (empty)

Several configuration files need to be modified:

(1) set the account password of / etc/exim4/passwd.client,smtp, and add:

Help 12 stu.xjtu.edu.cn:flowaters@stu.xjtu.edu.cn:password gmail-smtp.l.google.com:admin@vixp.net:password

(2) / etc/email-addresses, system email address, add:

User: admin@ip

Run update-exim4.conf after configuration, and then restart the exim4 service.

Considerations for using exim4 to send messages in web services:

1. The user name running the service is in the mail group before you have mail permission.

two。 The log of sending email is under / var/mail/username/.
