It could be an alias - so it wouldn't have to be a paid account.

That's correct, but the actual postmaster isn't normally someone at the final company, but at the email provider.

Think about some small sewing business with two old ladies. They order email from Office 365. Which one of them should get the postmaster emails? Neither of them can do anything about them. Should their nephew, the IT guy get it? He's not responsible for their email or any of their decisions. Only Microsoft has any reasonable hope of using that info. So an alias would break the postmaster and send the emails to the wrong place.

OK sure, but in those cases, there really isn't a true cost to the hosting provider - they could build the system in such a way to not show the account to the account holder yet get the emails to the hosting provider. Yes this would take coding... but it's not impossible.

Right, and maybe they do. But I think that the issue is... no one does and it is unclear who is responsible for conforming to the "rule".

yeah - is the hosting provider or the client? both will/could say it's the other, and then it's simply never done.

And I think it shows that the concept might not be valid any longer. Neither is likely capable of doing anything valuable with that email.

@pattonb said in spf include option:

se cidr notation for an include record in a SPF record, or is a fqdn acceptable ? or both ?

Both are acceptable.

@pattonb said in DNS PTR Record with 2 FQDN Entries with SPAM Check:

@JaredBusch incorrect, Scott has summarized succinctly

That is what you asked. But going with that is not what you actually wanted, then the answer to your original post is that you don't fix anything.

You whitelist the domain in question and move on.

The sender's ISP is in charge of setting the PTR record and there is not a damned thing you can do about it.

@pattonb GetDataBack by Run Time Software. Used it recently to recover data from an Apple MacBook Air SSD

Yeah I've used GetDataBack several times with different levels of recovery.

@dbeato looks like I need version 8.8.9 (or newer) in order to use the 2.0 Oauth to sync google calendar.
thanks everybody

Define “bridged”

@scottalanmiller said in KVM & Networking:

I have currently maybe 65 VMs on my KVM host, they each have their own IPs and are bridged. But there is a firewall and NAT sitting in front of all of it.

This is really how it is most cases regardless of hypervisor.

The only exception is in non-production when dealing with KVM + Wireless NIC... I haven't had time to see if I could get it to bridge somehow, so I'm stuck with NAT on my laptop. But, this is not an issue with servers, as they don't use wireless and this seems to be specific to wireless.
