By logging into the Webmail with the Postmaster account details and going
to the Management – Email Account Management menu, you can create a blacklist, or
rather a list of addresses considered as “unreliable”, in order to block any
email messages sent from these senders.
The Blacklist can be enabled both on single accounts and on aliases.
To enable it click on the icon in the Blacklist column next to
the account you wish to enable it on.
Specify the addresses to
add to the Black list:
the messages sent from a single address, enter the full email address and then click
on: “Add to list”
the messages sent from the accounts of a specific domain, enter an asterisk and
then the name of the domain you wish to block, e.g.: *@domainname.ext
also possible to block all the addresses of the accounts associated to a domain
and relevant subdomains even with different extensions. In this case you will need to put more asterisks as shown
in this example: *@*.domainname.*.
of the blocked addresses attempt to send an email to the account with the blacklist enabled, the email will not be received
and the sender will receive an error message specifying that the email has been
considered as “spam” by the recipient’s account.
