Important System Notification
As you might already be aware, UCEPROTECT made major changes to their blocklisting methodology this week which resulted in our IP network being placed on their blacklist,
which potentially affects all our customers who send emails to third party companies using UCEPROTECT.
While the activities from our part of the network are not solely responsible for reaching the required rate to block to get blacklsited,
we will take some major actions to prevent such issues in the future.
For the purpose:
We will force change ALL WEAK email accounts passwords for all mailboxes on our platform on Wednesday Feb 17th 2021.
Creating email account from the control panel will require even stronger passwords with our latest weak password detection update.
Thank you for your time and understanding regarding this matter.
