[help] ubuntu 15.04 can send mail but cannot receive mail

hi everyone, i'm newbie at ispconfig 3 i have no idea why cannot receive mail
but i can sending mail, what should i do?

 

Did you set up an MX record with your domain registrar?

 

i can do sending mail to other server (yahoo,googe,etc) but when im tries replying that messages, i got a reply, "undelivered mail returned to sender"
and this my mail.log

this is my records at ispconfig

did you mean i must registering the cname and mx to my domain manager?

 

Code:

[email protected]:~$ dig mx domainku.com
; <<>> DiG 9.9.5-3ubuntu0.14-Ubuntu <<>> mx domainku.com

You need to setup mx records that point to your e-mail server, not localhost. You are now telling everyone to look at localhost. Meaning that you are telling them to look at themselfs...

It should look like this:

Code:

[email protected]:~$ dig mx tsictdiensten.nl

; <<>> DiG 9.9.5-3ubuntu0.14-Ubuntu <<>> mx tsictdiensten.nl
;; global options: +cmd

;; ANSWER SECTION:
tsictdiensten.nl.  3600  IN  MX  10 mail.tsictdiensten.nl.

i just knew,thank you but, i don't know how to edit the mx should point to ip, not localhost

 

At your domain registrar, where you bought domain, you should have control panel with DNS management.
There you can edit DNS records.

 

such like a registrar name server?
thank's mate, i'll trying

 

i have trying, but still not work mate
this result of my dig mx

 

That should be fine.
Though, i do see something strange:

Code:

mail.creativauz.com is pointing to a cname which is 2x the domain: mail.creativauz.com.creativauz.com ?
mail.creativeauz.com should be poiting to where the cname is pointing:36.66.94.133

So results should be:
mail.creativauz.com. 3600 IN A 36.66.94.133
Remove the cname and make mail.creativauz.com an A record poiting to ip adress.

 

did this result has correct ?
mail.creativauz.com. 3600 IN A 36.66.94.133
but i try to sending mail still not found on inbox roundcube

and this reply

 

Just send you a test mail at [email protected]
Have not received any error messages. Let me know if you got it.

 

i've got this reply

i have restarting the amavis and this amavis's status

 

So, you cannot send a reply? Is that what you are asaying?

 

yaaa, cannot send reply from another server to [email protected]

 

What is domainku.com?
Because that is what you were talking about earlier? MX is still pointing to localhost.

Please post output of:

Code:

uname -a
cat /var/log/mail.log
cat /etc/postifx/main.cf
cat /etc/hostname

 

nothing mate, i am using creativauz.com
output uname -a

too long output , then i use tail -f n10 /var/log/mail.log, this output

 

output cat /etc/postfix/main.cf

this output from cat /etc/hostname
creativauz.com

 

in the postfix, myhostname should be mail.creativauz.com i think....
WHich guide did you follow?
If you run a multi server setup, hostname should be full fqdn , web.example.com, db.exampble.com.
If its single server, it sould be web.example.com or panel.example.com
