I second Tuffmail. I've used them for over a year now.
Never had any problems and the support when I've needed it has been excellent.
There's a wealth of settings you can tweak at SMTP level, they've umpteen webmail clients and the spam filtering is superb.
I looked around at many of the main paid-for IMAP providers before finally settling on Tuffmail and I've not been disappointed.
