protect mailboxes with a username with is not the email address to avoid accounts being frozon
Many accounts are attacked by hackers and are frozen.
Source IP addresses are so multiple that dynamic screen is not enought.
We blacklist IP's on the FIRST offense, for as long as one month on the third offence.
Accounts are frozen only after 24 bad authentications.
But …. this is not enought.
Il the usernames was something different than the emails, account would not be frozen.
Thanks for sharing your idea with us. This is already possible using Aliases. In order to use WorldClient users will need to select the default from address and default reply-to addresses by going to Options / Compose.
If you would like further assistance configuring this, please contact our technical support team. All of our support options are available at www.altn.com/support.
We tried to disallow access from aliases, and use a special "fake" invalid address as account name.
But in that case,
- users can not use WorldClient ;
- we can't verify credential
