Email on Addon domain - Connection Timed Out

[krembo99]

I have an addon domain on one account - and I have some problem with the mail.

All the mails are apperantly working, but I can not seem to be able to directly access them from an external Client ( Like thunderbird )

When I set up those mails using gmail for example, it works .

Also the webmail ( Roundcube ) appears to work fine . I can access it without any particular problems ( Besides the fact that If i go to mail.addondomain.com:2096/ I am promptly redirected to https://cpanel.mainserverdomain.com:2096/ - but still, logging there with pass and user works fine for the said mail. )

The problem is - I can not log in from an external , traditional client , like Outlook or Thunderbird .
The error is always :

Connection to server mail.addondomain.com timed out

.

and it takes some time for the error to appear ( when inputting a wrong address it is instantly )
I tried to restart services ( Cppop, Exim, Courier/dovecot ) - But no help .

my DNS zone looks like so :

localhost.addondomain.com. 	A 	127.0.0.1
mail.addondomain.com. 	CNAME 	addondomain.com
ftp.addondomain.com. 	CNAME 	addondomain.com
webdisk.addondomain.com. 	A 	xx.219.xx.xx

Should I add something there ? and if so - how ? ( Remember . it is an ADDON domain on another account )

Are there some different configuration for add-on mail accounts ??

Hello,

Are you able to ping addondomian and mail.addondomain.com from your local end ?

Nop . strangely enough - I can not ping none of the domains / accounts on my server ...

Hello

Check to make sure your IP address is not blocked by any firewall rules on your system. Also, try using telnet from your personal machine to the system. EX:

telnet 1.1.1.1 25

Replace "1.1.1.1" with the IP address of your server. You can replace "25" with a port associated with a different service as well (e.g. 110 for POP3).

Thank you.
