Forwarding aliases

A different address for every sign-up.

An alias forwards mail to your real inbox, so the shop never learns your address. If one starts getting spam, you switch that alias off and everything else keeps working.

Seven alias services

  • You can't run a mail server from home

    Mail-in-a-Box says you can't run it on most home internet connections. Residential networks are often blocked from sending mail, by the internet provider and by blocklists, because home computers get hijacked to send spam.

  • Your server's IP might already be blocklisted

    A cloud server can come with an IP address that's already on a spam blocklist, so you should check it and ask for a clean one if needed.

  • Reverse DNS, SPF, DKIM, and DMARC

    mailcow's setup docs say your server's reverse DNS (PTR) record has to match its hostname, and they recommend SPF, DKIM, and DMARC records to build a good sending reputation.

  • Gmail's rules for anyone sending to Gmail
