When sending from Gmail's web app on an account configured to send mail from another email account (in my case, another Gmail address), is there no way to conceal the original account's email address?
There are a lot of similar questions here, but either they relate to using a private domain with Google Apps, or I've already tried the solution proposed, which is switching the aliased account to a non-Gmail address (Outlook.com) and sending emails directly via the non-Gmail (here, Outlook's) secure SMTP servers. Nevertheless, recipients still see
On Behalf Of in my emails. I can post some cleaned up headers if helpful. (here's what I've tried; How do I get rid of on behalf of from my sent Gmail messages, How Can I Remove On Behalf of in Gmail , support.google.com/mail/answer/22370?hl=en&ctx=mail )
I don't have my own domain to authenticate my email against; I assumed that using the Outlook SMTP servers would suffice.
I'm sure there are good authentication and spam-related reasons for all this, but since I have control over both accounts, I can't see the reason for inserting this info. Do I really have to keep a separate private window open, or switch to a proper desktop client? And what to do for mobile?
FWIW, I tried this same experiment with an Outlook.com email account (configured with
Send As aliases), and not only do the native Microsoft aliases show up correctly in the recipient's email, but so do non-Microsoft aliases (meaning, while logged into Outlook.com's web app, I can send my email as FROM a Gmail account, and the recipient will see it as such).
I prefer Gmail's interface (filtering, keyboard shortcuts, etc), but this is enough to make me switch to an Outlook account (whose interface seems to have improved a lot since I last used it.)
