bieng a total newbie can anybody tell me about email forwarding,email eliases,mailinglists,pop3 and also how many of them should a host have.

email forwarding: all emails sent to user1@yourdomain.com will be forwarded to another mail box for example: user2@yourdomain.com
email alias: if user1@yourdomain.com is a alias for user2@yourdomain.com then you can read emails sent to user1@yourdomain.com either in user1@yourdomain.com mail box or user2@yourdomain.com mail box
mailinglist: used to send email to a list of email addresses.
pop3: you need this protocol if you want to receive emails by email clients like Outlook, Eudora
Those features are unlimited at any hosts.
Hope this helps.

thanx for the info dude:)
