I have a domain name which reflects my surname with godaddy and then setup an unlimited number of forwarding addresses to my real gmail account (I do this to filter my mails depending on who I give it to).
In gmail, under Settings / Accounts & Imports / "Send Mail As", I have up until earlier this year, some 20 aliases that I could "send mail as" e.g. gmail address is firstname.lastname@example.org but I have email@example.com, firstname.lastname@example.org, email@example.com etc etc. Within my firstname.lastname@example.org account, I can compose a new mail and send it as one of those above e.g. email@example.com and gmail allows it. Any replies also come back to firstname.lastname@example.org which forwards to my gmail inbox.
Anyway, since the last few months, I am unable to setup new forwarding addresses in gmail as it asks for my email address and then the server settings. Has something changed because it does not allow it?
