Linux Mail Server Configuration guide

Currently, the most common mail service protocols on the network are SMTP (send protocol) and POP3 (Receive protocol).

First, start SMTP:

After you install and start the SendMail service, SMTP should be turned on. If the letter is not sent out, it may be a DNS problem, please do the following on the Linux machine:

(1) cd/var/named

MV Named.ca Named.ca.bak

Touch named.ca

Killall-hup named

(2) Executes netconf->server tasks->domain Name Server (DNS) in the X Window->config->domains->add a new ( Or click on existing domain to modify)->name servers (NS) fill in the first line of Gblinux.126.com,mail servers (MX) write gblinux.126.com, the second line is written 126.com ( My virtual mail domain). Default IPs can be filled out. Exit and activate it.

The DNS service should now start correctly.

Second, start POP3:

(1) Modify the/etc/inetd.conf, and then cancel the line of POP3 and modify it to:

pop-3 Stream TCP nowait root/usr/sbin/tcpd/usr/lib/linuxconf/lib/vpop3d/usr/sbin/ipop3d

(2) Configuration "Virtual e-mail domain name" (fictitious email domains): Run linuxconf or run directly mailconf, choose virtual email domain, and add a domain name (as mentioned in the above 126.com) It's OK.

(3) Add e-mail users: Run userconf and then click Special Accounts------->virtual POP accounts (mail only)-----> just in the second step add the domain name, OK, Now you can click the Add button to add a new user.
