I would redirect my mail.quantumwarp.com to quantumwarp.com where as some might use the www option. I would sssume redirecting to the non-www should be the default option along with the option of no redirtect (ie leave as alias) and redirect to www
If I understand correctly, it’s not a redirect, it’s DNS entry.
mail. and www. and @ would normally all point to the same IP (the host) so using a web browser mail.domain or www.doman or just domain would all point to the same website.
Yes, that is what is being requested, and we have discussed it before in the thread OP linked, and we decided we would add it. It just hasn’t happened yet (because nobody has implemented it yet).
in Virtualmin –> Web Configuration –> Configure SSL Website –> Edit Directives
NB: These rules follow the current redirect format. They work perfectly fine but there will be some revisions to the redirect format so they are syntactically better, but function exactly the same.
