I’m trying to set up my own Email server(s). It looks I need to add 2 DNS records, one MX and one A records ??
Type Hostname Value TTL (seconds) * MX longervision.com mail.longervision.com. 10 14400 * A mail.longervision.com 188.8.131.52 3699
However, after I specify these 2 records, I checked Networking->Domains again:
Domains: Directs to longervision.com multiple locations 2 A / 1 CNAME / 1 MX / 3 NS
Why multiple locations? And is it OK to keep it as multiple locations?
After a while, I tried to telnet on the server:
jiapei@SERVERNAME:~$ telnet mail.longervision.com 25 Trying 184.108.40.206... Connected to mail.longervision.com. Escape character is '^]'. 220 mail.longervision.com ESMTP ehlo mail.longervision.com 250-mail.longervision.com 250-SIZE 11534336 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN
After a while, I tried to telnet from my laptop
➜ ~ telnet mail.longervision.com 25 Trying 220.127.116.11... telnet: Unable to connect to remote host: Connection timed out
But, telnet hangs there…
I seriously have NO idea where I’m wrong? Can anybody give me a hand please?
