"looks promising, fails miserably"
mostly easy to use
lost the very first email someone else sent to me. Gone. Did some online research, and it's a known issue with massive work-arounds that are seriously not worth the risk or effort.
Simple stuff is made way too complicated (like formatting a signature - basic task that required googling and a work around again)
If you like to dabble in free software, and don't mind risking losing some mail here and there, go for it.
If you actually need a reliable mail program, look elsewhere. Thunderbird has failed me on day one, first email! So disappointed as I'd come to really respect Mozilla. Other bugs could be overlooked, but losing mail just can't.
