While it seems convenient at first glance, forwarding your @mydomain.com emails to gmail.com - or hotmail.com etc., can result in a lot of your forwarded mail ending up in spam - or not being delivered at all!
Because forwarding your emails is automated system that forwards both legitimate and spammy emails, other providers may find the amount of non-legitimate email being forwarded unacceptable – and block you. This not only affects your forwarder, but your ability to send to @gmail.com or @hotmail.com directly!
Instead, the better option is to have Gmail pull emails from your @mydomain.com account directly, and save the forwarding. Here’s how to set that up.
Important: This solution might not be the best option for your needs, it assumes that you as the mail admin are OK with the recipient knowing the login info for this emails address. If that is not ideal, using a forwarder allows the mail admin to maintain control or who receives what, and the mail admin can revoke a forwarder at any time.
IMPORTANT TIP: This process will prompt GMAIL to import all emails in your email’s Inbox. If you have a large inbox, or you’re the sort of person who leaves all of your emails in the Inbox, consider clearing your Inbox first by moving emails into a new folder.
