Question
Hi guys, thank you for this great gem.
I was reading through the documentation and saw "Verifier domain should refer to verifier host IP address" can you please elaborate on this? Does this mean we need a root A record on the domain to point to ip address? Or is this something else?
Also, what about subdomains:
I.e a.mail.com, b.mail.com can each point to separate IP addresses with different emails and be used for verification without causing the whole domain to be blacklisted if one get's blacklisted?
You're welcome, @eni9889! The best gratitude is starring this repo) Yes it's means that verifier domain (or subdomain) should have A record with ip-address the same as on host which truemail runs. You should follow this rule for the best email SMTP validation outcome. About your question about subdomains, it depends on blacklist configuration policy of host which will accept your smtp request. Cheers!
@bestwebua done :) also any recommendations for cloud providers that have port 25 open to set up the verifier on or does having a fully functional mail server not matter?
Yup, @eni9889! To have an MX records with a real mail server for verifier domain with existent verifier email should provide great result. More info about verifier host preconditions you can find here: https://truemail-rb.org/truemail-gem/#/quick-start?id=verifier-host-preconditions
