;) Thanks Bill. Was hoping a 3rd party would post the actual 'rule' they
are breaking, eg RFC etc..
Always better if from a more impartial expert source ;)
For the record, this week (MailChimp/MailGun) have been very bad with
escaping phishing/malware reports.. Pretty soon have to auto-add the
IP(s) that are detected as sending Phishing like we do to SendGrid..
hehehe...

is rumored to have said:
I know this doesn't look professional, but the question from the team
member does this contravene any rules or best practices.
list-manage.com
This domain does not have any A records.
It has a single MX record pointed at:
mail.admin.mailchimp.com
That hostname exists, but it doesn't have an A RECORD.
It in turn has just a single MX Record.
inbound-mx1.mailchimpapp.net
Kind of a strange MX delegation.. I assume to avoid CNAME's
Avoid CNAMEs isn't the rule. The rule is that the name resolved by a MX
MUST be a primary hostname, i.e. it MUST have an A record.
So this isn't just 'strange,' it simply should not work.
But it does seem very strange. Comments anyone? I didn't have an
answer for him..

Have a great long weekend all.. Was going to write a matching long
'state' of the union (activity) but it is too sunny out.. short form is..
* Sendgrid Really bad this week again
* Mailgun having similar situation?
* More PREFIX BROKERS MNT IP space coming out, same bad guys as usual,
Serverion et al. Some complimentary activity from Russion hosters.
* OVH Still handing out IP ranges to show shoe spammers
* Short Bot Traffic run beginning of week, but quieted quickly
* Gmail, Gmail Gmail..
* Increase in random compromises on VPS providers, OVH, DreamHost,
StratoServer
* Increase in Japanese based spammers..
