Ask HN: How to “alias” an email with a different provider?

[trevi]

I have an email account, provided by a mobile/internet provider, which can only be used when connected to the said operator, either via mobile or from a fixed connection. Use = receive incoming emails or send them. The SMTP server only accepts requests when I am connected to the provider 4G or fixed internet connection.

I would like to keep using the account, but basically just forward all emails to a gmail account (easy) and send emails from the gmail account, but forwarded through my old email.

I can use a raspberry pi connected to the home network which is run by the said provider.

Any ideas?

I don’t see why you haven’t already answered your own question with the pi. Just ssh in to the pi and send your emails, no?

I would like to be able to just send an email from anywhere, eg my mail client on the phone, without any extra steps

Maybe:

Set up the smtp account on the phone to be the pi. Set up postfix on the pi to use the ISP as a smarthost.

Does the carrier have a web UI for the email? If so, there may be a toggle for forwarding in there.

Only for incoming email unfortunately
