I was initially really confused how to setup filters as I found a guide and it was talking about filters for labels, I quickly realised that this is a "feature" to set Opera Mail away from other email clients, I like the idea and I like the feature but labels really do not fit the bill when your accessing your email everywhere and through multiple programs.
My problem is I access my email on my phone, my tablet, I access it on my PC and its a shared account so other employees also access the account from their machines and their devices.
Everywhere and everyone else filters email into IMAP folders and we have been doing this for years, besides no other software supports filters so filters arnt even a possible feature for others to adapt to.
What I'm saying is, for a personal use this feature is good if all you ever use is Opera Mail, but this is not practical, we dont live in a fixed base fixed machine society anymore that was 1998.
Can we please put traditional mail filtering back into Opera, it is literally the only downfall to this program! I really want to stop using thunderbird, stop using outlook and live a happy life with Opera Mail!!
