Free Email Forwarding Services
Forward your email from one email account to another.
Free email for members of the American Radio Relay League (in a sense, it's not free, since you have to pay to be a member of the ARRL - but you might not know about this particular benefit of membership.)
Bigfoot allows you to forward emails to an existing account. The free service has a limit of 50 forwarded messages per day, and 3MB per message. BigFoot filters forwarded emails against several anti-spam blacklists. Note that by signing up for the free service, you're automatically opting in to receive marketing emails from Bigfoot partner companies. BigFoot also offers several paid service levels which add POP3/IMAP access and other features.
Bigfoot offers two premium service levels, from US$9.95 a quarter and up, that greatly increase the number of emails that can be forwarded each day, and that introduce additional features such as consolidation of multiple email accounts, email filtering and autoresponders.
