Aliases and privacy?

Anyway an alias can be connected to the primary address or to the IP address?

Yes, it can to the primary address. But Alias meaning another e-mail?

Exactly how? As far as I can tell neither my IP address or my primary Fastmail address appears in the receiving header when I send an email using an alias.

Hi md2, welcome to the forum!

The intention of your initial question wasn't clear to me, but yes, you're right. The receiver of an email won't see your primary FastMail address or your IP, at least as long as you use the FastMail web client. Not sure if there are some POP or IMAP clients that may reveal that information in their headers.

Cheers,
Michael

Welcome to the EMD Forums!

If you use the FastMail web interface to send from an alias at your account, the recipient will not be able to determine your FastMail primary (login) address or your computer IP address. They can see in the full headers that the message was originated at FastMail using the web interface and sent through their outgoing server.

If you use a local email client connected to FastMail to send a message the results are the same except that your PC IP address will be visible to the recipient. The FastMail outgoing SMTP server will add a header with that information, as is done for most servers when relaying a message.

I almost thought so, but better to be sure. Thanks for the info.

Very good to know about local email clients since I'm using Thunderbird most of the time due to the lack of search in the calendar. Thanks.
