Hello everyone, I've recently installed Roundcube webmail on a VPS server running HestiaCP and I'm in the process of configuring the DNS records for one of my domains. I'm seeking your guidance to ensure my DNS configuration properly supports Roundcube.
I've configured DNS records for my domain through my hosting provider. The configuration includes:
A Records:
Root domain pointing to server IP
"mail" subdomain pointing to server IP
CNAME Records:
"www" pointing to mail.subdomain
"ftp" pointing to mail.subdomain
"webmail" pointing to a mail-related subdomain
MX Record:
Pointing to the mail subdomain
TXT Records:
SPF record
DMARC policy
SRV Records:
Various email protocol records
Could you please confirm what CNAME records Roundcube expects for a standard webmail installation? I've configured a webmail CNAME record, but I want to verify this is correct. Is there a specific DNS record I should create for Roundcube to function properly? I've seen some installations use webmail.domain.tld as the access point, but I'm unsure if this is a requirement or just a convention.
When I try to access Roundcube, I'm encountering configuration issues. I've attempted to set up the HestiaCP templates for Roundcube but received errors about missing template files. I would greatly appreciate your guidance on the proper DNS configuration to ensure Roundcube works seamlessly with my setup. If there are any documentation resources you could point me to regarding DNS requirements for Roundcube, that would also be extremely helpful.
