>1 You can filter attachments by MIME content and filter usage by group
You can filter attachments within virtual hosts as you would as in the default virtual host. There are no restrictions on how the rules are created and who the are applied to. Obviously a global policy would only apply to the domains listed for the specific virtual host, but everything else will be the same.
>2 block the receipt of compressed files containing password, such as extensions Zip, RAR.
The blocking of password protected messages is only configurable on a global level, it can not be configured per virtual host. Additionally, the IronMail only has the ability to extract data from zip files.
>3 Use of Disclaimer can be configured for only one domain registered in Virtual host
You should be able to create and apply disclaimers in the same way as the default virtual host. Much like the attachment analysis mentioned above, global policies are available, as are any groups you would want to make.
>4 Is there any report with the 10 sender Recepeit who sent emails. Remembering that it was only for a Using Virtual Host field.
There are unfortunately no reporting options for the individual virtual hosts, only on a global scale.
