Can email account be for addon domain (needed for SSL)?

Hi!

I have cPanel version 11.30.5 (build 6) access.

I have domain, this domain has subdomain and there is one another addon domain, which points to the mentioned subdomain. I managed to create e-mail account in cPanel for subdomain (cPanel displayed addon domain name in the available domain names for email account, one can access the new account from subdomain.com/webail, altough the only option here is password update, no incoming or outgoing mails).

The problem is, that my Outlook express provides error message remote server said: 550 This domain is not hosted here as a reply to any attempt to send mail to the new account. It happens even for rather old accounts. It is not possible to configure email clients for this account as well - simply email client can not complete initial tests of receiving and sending mails.

It is confusing a bit. Is it possible to create email accounts on add-on domains at all? And if yes, how to troubleshoot problems? And if not - then why on the Earth cPanel allows to do that.

I would like to assign ssl sertificate to add-on domain and that it why I need email account precisely for subdomain. Actually - is it possible to assign SSL for add-on domain (I don't need SSL for any other domains, subdomains or add-on domains that are sitting on the same IP).

Thanks in advance.

 

Some website is accessible from addon domain and maybe that is why some Apache redirection rules are prohibiting to access email account normally. It is also funny that it can be visible from cPanel that addon domain email account has some 700 bytes used quota, not 0. How it is possible to see the content of this email account?

 

And just another update about troubleshooting the issue - I made new outlook account and as incoming and outgoing email servers for my addon domain email account I selected not the addon domain names but domain names and after this outlook could complete tests and create new account. I checked the email directory content on the cPanel and there were Outlook test mails on the addon domain account!

So - this is really confusting - after all - is there possible to create addon domain email accounts?

 

Microsoft Outlook Error message (about undelivered email to addon domain mail account) was:
remote server said: 550 This domain is not hosted here

Usually I can ping mail.mydomain.com and in my situation I can ping both mydomain.com and mail.mydomain.com now, and also I can ping myaddondomain.com, but I cannot ping mail.myaddondomain.com (answer is "Ping request could not find host mail.myaddondomain.com"). I guess that cPanel creates additional DNS entries (about server and maybe - about mailserver as well) upon creation of addon domain and I guess that in this time the DNS entries for server were created but entries for mail server were not create and the solution can be to add entries for mail server manually. But where can I check or do this?
