ISPconfig3, email validation issue

[Justin Albstmeijer]

Tested trunk checkout of today.

when creating a DNS Zone,

Email: [ ] e.g. postmaster.mydomain.com.

- example is not an email
- when leaving email empty it gets accepted
- when trying to enter a valid email address (including '@') it gets rejected

Error:
Email format invalid.

[till]

Thats all correct except that a empty value is accepted, I added this to the bugtracker. As the example points out, the email has to entered in a special format, which is used by most DNS servers like BIND and MyDNS. Instead of:

yourname@yourdomain.com

you must enter:

yourname.yourdomain.com.

Ah, ok clear..

how does dns handle email addresses like justin.albstmeijer@domain.com?

justin.albstmeijer.domain.com could be interpreted as justin@albstmeijer.domain.com or justin.albstmeijer@domain.com

seems somewhat confusing for users..
Wouldn't it be better to default to postmaster.domain.com and give a warning within the email management tab that there needs to be a forward for postmaster@domain.com as long as it does not exist?
