Sent email return with the error:
MailEnable: Message delivery has been delayed.
This message means that the SMTP connector is not configured correctly. The following setting should be correctly setup:
Mail Enable Administrator > Servers > localhost > Connectors > SMTP > Properties
- DNS server should be valid. It must resolve any correct host name.
- Fully Qualified Domain Name (FQDN) should be properly resolved in DNS.
Bound IPs for SMTP should have correctly resolvable PTR DNS records (Mail Enable Administrator > Servers > localhost > Connectors > SMTP > Properties > Inbound tab)
This can be checked using http://www.dnsstuff.com
Go to Reverse DNS lookup section and type your IP(s) that are bound by SMTP. Request should return a valid host name or domain.
If these parameters are set up correctly, the file should also be correct:
"%plesk_dir%\Mail Servers\Mail Enable\Config\ADDRESS-MAP.TAB"
The first line should be the following:
[SMTP:*] 0 System
Check, if your server can access remote SMTP servers.
You can check it using telnet tool
C:\> telnet mx1.mail.yahoo.com 25 Trying 126.96.36.199... Connected to mx1.mail.yahoo.com. Escape character is '^]'. 220 mta173.mail.re4.yahoo.com ESMTP YSmtp service ready
Connection output should be similar.
