Question
MX only or MX+A for Email server? Beside, why multiple locations?
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 159.65.68.90 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 159.65.68.90...
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 159.65.68.90...
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?
