Yes, but when I put lots of effort into making custom rules and sorting
stuff then that does not get translated to any other client.
If I want to make, say, a mailing list filter I have to do it on the server
if I want the changes to automatically propagate to other clients. Otherwise
it starts getting messy.. some clients will properly update the local
folders and on the server, while others will not.. all depending on what I
happen to be using at the time and whether not I remember or have enough
time to manually copy rules around.
It's all a PITA and things should be better then this.
Not to also mention that email clients on "Desktop Linux" suck. Evolution is
the only one that has the features that typical users expect nowadays, but
it's a not programmed well.
