Sending my mail from another fm account

Terry · 9 Apr 2025, 11:34 AM

I would like my wife to share one of my alias in her mailbox.

I remember I had to generate a password, but I forget the rest of the steps involved....can I still do this or have things changed.

The easier way to do this is probably to set up another user at your Fastmail account. But this may cost you and may have security issues. I don?t use multiple users so can?t help you with that.

There are two separate issues:

Sending using a From address at a different account
Receiving incoming messages sent to an address at a different account

In general, see this help link and use Add an address you already own:
https://www.fastmail.help/hc/en-us/a...dresses#create

That should allow you to send using an alias at a different account. But please note that DMARC may not work correctly, depending on the domain of the alias. So message sent using this method may be rejected as spam. This is due to the efforts being spent to prevent senders from faking the From address.

To receive messages sent to that alias, you will probably need to create forwarding for that alias at the main account.

If it?s not the main account (login) address, you can use alias forwarding by adding a delivery address at Settings>Users & Sharing. Choose the alias and in advanced preferences add the new delivery address. Then be sure to click Save (probably in the upper right corner of the page, depending on how you log in).
Or set up a rule which forwards incoming message sent to that alias to the secondary account.
Forwarding messages can break DMARC, as SPF in general will fail. So spam detection may not work as well.

Thanks Bill, yes I got DMARC did not work correctly.

I have given the email address to my wife now and set up a direct.

I hope it works for you, Terry. I was assuming that you were using Fastmail domains to send. If you own your own domain, you should be able to set it up to send well from either account by appropriate DNS records for that domain. But you can only receive email at one specific server, so you will always need to redirect messages received at the main account to the secondary account.

If anyone has direct experience of doing any of this, I would encourage them to chime in. I have two Fastmail accounts and have experimented a little with this, but it was only an experiment with a few test messages.
