I found an interesting thing in hestiacp mail service,
I don’t know this is feature (intended/untended) or bug.
I have 3 domain and each has mail domain same:
mydomain1.com and webmail.mydomain1.com (for mail login)
mydomain2.com and webmail.mydomain2.com
mydomain3.com and webmail.mydomain3.com
Also each domain has 1 email account:
So when I open any webmail domain (eg: webmail.mydomain2.com)
I am able to login and use any email account of any other mail domain (like: [email protected])
So I can login and send email from any account of any domain by any other domain.
I open “webmail.mydomain2.com” then login on “[email protected]” and use it.
There is no restriction like I am only able to login that email account which is come under opened domain mail.
Like: webmail.mydomain1.com can only able to login/open “[email protected]” not "admin@mydomain2/3.com.
So is this feature or bug?
