@Jay Dubb The issues we experienced will be addressed hopefully in the next build as the amazing team were able to duplicate those issues on their end. So, I would hold off till everything is fixed.
One issue was: if an account never had a folder or file created for emails, an example being, the account never captured incoming emails, this included some admin accounts and accounts used for sending emails from websites) stopped working. those accounts needed to be removed and set back up again.
(SmarterTools Dev team were able to fix this, so this should be in the next build)
This issue also lead to the entire domain not showing up in SmarterMail, if the admin account never had a folder created for emails. All other accounts within the domain sent and received emails, but from the SmarterMail admin site, you were not able to see the accounts. There is a fix to this, but it takes time, as in our case!
Another issue was: IDS Rules were duplicating upon every restart, meaning, when if you changed or updated any of the original Security IDS Rules upon restarting SmarterMail they added Original IDS Rules back in again, keeping the ones you already changed. So in our case, with all the domains which needed to be adjusted, to get them to show again, we ended up seeing 30 extra IDS Rules, especially for 'Password Brute Force by Email' and 'Password Retrieval Brute Force' in our case.
(SmarterTools Dev team still looking into this)
