email client to replace outlook express

hello--

outlook have messed up my emails one time too many !
I like linux so much, I'd like to run my mail client on it.

Which email client would you recommend ?

Hopefully something that doesn't have it's proprietary format for storing emails, that doesn't get confused when it's storing a lot of mail, and if possible where you can configure mail checks with different frequency on different accounts,

thanks,

all best,

I'm using Mozilla Mail which works fine for me, but I've also heard good things about Thunderbird (another Mozilla project).

I've just started using Thunderbird and it's fairly good. Just set it up for a colleague who has used Outlook for years and he's happy using it, so an easy transition if that matters.

what I'm actually looking for is something quite solid.

Outlook Express, when a .dbx gets fairly large, eventually just gets mixed up, no matter how kindly you treat it. This results in partial data loss (after recovery). This has happened on all the systems I've seen with large .dbx files. (over 500MB).

This just happened to me, so now I'm angry...

thanks for answering, any additional opinions are welcome

all best,

I also quit Outlook a long time ago.
I am now perfectly fine with Pegasus Mail.
They are doing a very good job and have made a very very nice mail server.
