We are happy to share that we just released Mailster v1.4.1.
Block Spammers with Wildcard-Addresses
We have made improvements to the "Blocked Email Addresses" feature which is a global setting (cross all your mailing lists) to protect you from SPAM. Previously you could already block single email addresses and email addresses begining with a certain phrase.
In order to make this even more flexible, we now also allow more flexible wildcard addresses.
Wildcard means, that only a part of the sender address has to be match - the domain and/or the local part (the name before the @-character) is checked for.
One example is the wildcard address *mail.ru - this mean, that all email addresses ending with @mail.ru will be filtered out.
Another example is the wildcard address no-reply@* - this means that all email addresses that start with no-reply@ will not be forwarded.
You can also combine this, e.g. *@*.in or *@example.*
