I'm a Thunderbird user almost since day one, but now I'm looking for 
something else. For whatever reason, it doesn't work well for me - every 
once in a while it becomes non-responsive (UI completely frozen for 
several seconds, CPU usage goes to 100%) and I just can't afford to 
waste time waiting for the email software to start working again.

My main desktop platform is Linux, but I need a client that works the 
same and looks the same on Windows too. Email server is IMAP with a 
pretty hefty account: over a hundred folders, hundreds of thousands of 
messages total (server-side filtering with Sieve). Typically it's a 
remote session, over VPN. So the client better work well, and be 

The issues with Thunderbird might be related to the size of my IMAP 
account, plus the VPN latency - but frankly, I don't care, the client 
needs to hide all that stuff from me, do the updates or whatever in the 
background, instead of blocking the UI until it's done. Ironically, it 
blocked when I was done with this paragraph and I hit Enter. Sticking it 
to the man one last time, I guess.

Any suggestions? Thanks.
