How do I modify the default From address from the users service

[mglraimundo]

1. Set up a hosted e-mail service for your custom domain (Zoho, which is free, or Google, …)
2. Add accounts@customdomain.tld as an e-mail address there
3. Configure SPF and DKIM (these should lower the odds of getting triaged as junk e-mail)
4. Enable the use of a custom SMTP server in Anvil [see image below]
