To send email from @mirahezebots.org or have an alias, ask RhinosF1 or MacFan4000.
The staff@ address is managed by google and should only have @mirahezebots.org emails in. Each SRE must manually opt-in and accept forwarding from the google staff email.
To gain a mirahezebots.org alias, verify the email in Cloudflare as a destination address and then add the forwarder.
If you need to send email, web.fosshost.org is trusted for this. You can ask someone with DirectAdmin to get a password generated for your user. You can then use your gmail account or other provider and setup an alias with web.fosshost.org as the SMTP server. On gmail, this can be done via 'Accounts and Import'.
