Your cridland email address will forward to your current email address - so, if you're currently bigjim@hotmail.com, you can get jim@cridland.net mail automatically forwarded to appear there.
You don't need to change your email address, nor fiddle with your mail program.
Should you change your 'real' email address in future, just mail postmaster@cridland.net and let him know. Your cridland email will follow you.
cridland addresses are scanned through SpamAssassin. All emails are still delivered; spammy emails are marked with [5pam] (that's a number 5 followed by 'pam' to get over Gmail's inability to recognise square brackets in filters).
@cridland.net or @cridland.eu domains are available. You'll not, automatically, get both (unless you want them).
It's easy to change your outgoing address, so that all your mail is stamped with your new cridland address.
If you have a website, you can use a subdomain like http://james.cridland.net/ - this can be configured to simply forward to your current webspace, or be a fixed IP address or CNAME for another server. Websites aren't automatically set up by the webmaster, but if you want one, let him know. Subdomains of your own subdomain are also available.
You are asked to keep your 'real' email address valid during the lifetime of your cridland.net address. You will receive very low-level email advising you of any changes to the cridland.net email system, normally less than once a year. By signing up you signify that you are happy to receive these emails.
The webmaster uses a cridland.net address for his own use, relies on it for business, and therefore is planning to renew cridland.net forever. cridland.net is run by a web professional, and email is currently hosted in England on a high-quality, private, server. However, the email service is provided "as is" without any warranty whatsoever. The webmaster disclaims and expressly excludes any implied warranty, term or condition as to merchantable or satisfactory quality, or fitness for purpose.
