Your DNS records are seriously messed up!
This looks ok so far...
Code:
server1:~# dig mx 1asplet.net

; <<>> DiG 9.6-ESV-R1 <<>> mx 1asplet.net
;; global options: +cmd
;; Got answer:

... but:
An MX record must always point to an A record, never to a CNAME record, and both smtp.1asplet.net and mail.1asplet.net are CNAME records. Furthermore, smtp.1asplet.net points to itself which makes absolutely no sense.

mail.1asplet.net points to pop.1asplet.net which again points to itself.

Code:
server1:~# dig smtp.1asplet.net

; <<>> DiG 9.6-ESV-R1 <<>> smtp.1asplet.net
;; global options: +cmd
;; Got answer:
