Which host with SMTP relay

[s0ck]

Hi
Need to consolidate a few domains I have here and there so thinking a reseller package might be worth looking into.
Specifically, ability to setup an SMTP feed and the webmail must look purty (Plus.net's is pretty good for example).

Any ideas?

Thanks for the reply.
The webmail I am familiar with I believe is AtMail 4.61; off the top of your head, do you know of any hosts that run this?
