The problems with Evolution are not to do with its RAM use. They are (in no
particular order);
* clunky interface
* randomly losing mail during IMAP sync
* crappy folder support with IMAP
* bugs with the spamfilter dependencies
* supporting some services but not others for no obvious reason
Having switched from Evolution to IceDove just recently, I doubt I'll go
back. I just need to install Lightening and I'll have the full suite of
(useful) functions Evolution offers. IceDove has its own issues though. Off
the top of my head:
* seems to use a lot of RAM
* it made a mess of importing the .vcf files of my address books from
Evolution, losing every bit of data except the email addresses, and losing a
number of the entries completely
* there are far too many disparate places for adjusting difference kinds of
settings and preferences
* pops up incoming emails in tabs, but when I compose it pops up a separate
window
