This is probably going to be a daft question: My etc/hosts file has the following entries 127.0.0.1 localhost 11.22.33.44. host1.myDomain.com host1 Does that look correct? Sorry - I’ve been awake far too long dealing with a misbehaving setup and Roundcube. Thanks in advance Dibs

Weird behaviour going on. Disabled BIND\DNS and sent an email to yahoo. Upon checking the raw headers I got, dkim=neutral (no sig) header.i=@myDomain.com ; which made me think DKIM was working. So went into Virtualmin >> Email Settings >> DomainKeys Identified Mail which was as before but I clicke…

Looks good for a server hostname. If that’s your only host your hosts file is done. But if there’s a virtualhost in Virtualmin for myDomain.com or any other host using the same IP, add them alongside host1.myDomain.com .

@ramin - many thanks for the reply. At the risk of being totally dense - if I had add a Virtual Server with a domain newDomain.com , would\should the hosts file look like? 127.0.0.1 localhost 11.22.33.44. host1.myDomain.com newDomain.com host1 and similarly the 2nd line just get longer with each …

[image] ramin: But if there’s a virtualhost in Virtualmin for myDomain.com or any other host using the same IP, add them alongside host1.myDomain.com . That’s not necessary. They should all end up in DNS somehow.

[image] Dibs: similarly the 2nd line just get longer with each new domain (Virtual Server) that gets added? No. Your /etc/hosts is fine and it doesn’t need to change.

@Joe - thanks for the replies. The “fly in the ointment” might be that the domains have their DNS managed at the Registrars control panels. I’d probably prefer to keep it that way - not wanting to run at least 2 servers. Can I have BIND running but effectively not doing anything? DNS Forwarders sp…

You could have BIND running for only local usage (it’s small/efficient in that context), or you can just make sure you add your DNS records (including glue records) before expecting anything to work in Virtualmin. There are some features (“Preview Website”, in particular) that can’t work unless Virt…

@Joe - Thanks for the reply. I don’t really want to run BIND, but need to use DKIM and my understanding is that to enable and use DKIM, BIND must run and DNS must be enabled for DKIM to work for each Virtual Server. If this isn’t the case - happy to turn it off. Is there anything I need to do to u…

Oh, DKIM does require quite a bit of DNS interaction. But, I think you can create and maintain the necessary text records yourself. Running a local BIND wouldn’t make DKIM work, unless you’re pushing those records out to your “real” DNS server. DKIM works by providing the public key of the private …

@Joe - thanks for the info. In all fairness - I maintain the DKIM TXT records on the domain registrars control panels manually. No issues with that going forward. Sorry if you’ve already answered the question - if I am maintaining the DKIM TXT records manually at the registrar control panels, do I…

[image] Dibs: if I am maintaining the DKIM TXT records manually at the registrar control panels, do I still need to run BIND and\or enable DNS for a given (or all) Virtual Servers? I’m not sure. I’ve never done it. But, I can’t think of why it would be necessary. But, Jamie may have made it a…

@Dibs – @Joe hit the nail. DNS A records are far more relevant than the hosts file.
