Why does right part of my email address contain subdomain information IMAP?

[fifou]

Hello!

I create a CNAME imap.my_domain.com to redirect throw my_domain.com.

When I try following parameter in main.inc.php, my address is [email protected]_domain.com in login page and in scrolling menu of identities (before composing a new email) :

$rcmail_config['default_host'] = 'ssl://imap.my_domain.com';

So I change it to ssl://my_domain.com in order to obtain an address without "imap" subdomain but I thought I will have to use a special CNAME to do things properly. Is roundcube adapted to work like that? Is anything I misunderstood?

Thanks a lot for any kind of help.

Regards,
Phil. (forget my poor english please, I did my best to be clear).

Same issue I have added imap.domain name in default host of IMAP and during login email it shows imap in login email. I have to manuallyy chage it.

If your IMAP login name is [email protected]

Then use example.com in that config.
