Comments and Reviews
Roundcube works BUT it lacks features that would make it much easier to manage email with.
The lack of filters not just for spam but for managing all those emails we want but don't necessarily want to read before filing them in their own folders such as tech newsletters etc.
Even better would be a way to filter based on the To field (for those of us who use it for multiple accounts or for any mail to the domain that isn't currently a "real" email. Great for those who get emails to spam@domain.com, support@domain.com, suport@domain.com etc.
I would love to be able to have all the "not right now" emails going to their own folders and also to be able to fix wrongly identified SPAM so it does not hit the junk file.
The program works but the potential to be so much more an efficient and effective tool is there.
RoundCube is very precise for editing, attaching pictures inside the message ect.
