Is it possible to set up a reverse proxy on accounting.mydomain.tld to mask the mycompany.quickfile.co.uk url? Naturally all post data and /url/locations/ would be forwarded to quickfile by the nginx/apache reverse proxy.
I understand that custom urls are not currently supported and this is a deal breaker for me as I want customers going to my domain not a third party, so I’m looking for any ways around it. Alternatively, can the API be used for this?
Are emails sent using my smtp server and email address or are they sent from quickfile.co.uk’s smtp server(s) and/or email addresses? Would I need to add additional IPv4 to my spf DNS entry? How would this affect my dmarc and domainkey DNS settings?
