It’s not uncommon to have two, three, or even more email accounts and it can be tedious to have to login to many different locations to check your mail. So you setup email forwardings to the main email account you're using and you'll just need to login your main email account to check email messages sent to each of your email accounts. Email forwarding is indeed a good solution for this situation but you may find a lot of forwared email messages are marked as spams. To solve this problem, we recommend you use POP3 Retrievals as an alternative. This service allows you to retrieve mail from other mail servers and deliver them into one or more local accounts. This is useful for centralizing mail from multiple locations into one place, making it easier for users to check their mail.
Email service providers like Hotmail/MSN/AOL/Yahoo/Gmail are offering POP3 Retrievals service and you can login these email accounts to setup POP3 Retrievals to poll email messages from our mail server.
