Why shouldn’t I use Yahoo!, AOL, Aim email as my From address?
Recently Yahoo! and AOL introduced a change in the settings of their Domain Name System (DNS) which specified that Internet Service Providers (ISP) should reject all messages that have a “From” address using an @yahoo.com, @aim.com, @aol domains — if they weren’t sent from Yahoo! and AOL Mail servers.
This situation has a negative impact on the deliverability of your messages because every email you send with a Yahoo!, Aol, Aim from address bounces.
Solution: use any other email address hosted at a domain which is not Yahoo!, AOL, Aim. Also, in order to achieve better results in delivering messages you should avoid using any free domains like gmail, hotmail etc.
