SOLVED THe problems below were resolved by asking AWS to remove outgoing restrictions on my AWS Lightsail CPanel install. Simple as that.

    dig +nssearch 0.168.192.in-addr.arpa also gived me results I dont understand. I used my IP but that (modified as directed) and it gived me .ru servers and two IP's. Doesn't seem to have much bearing on the instructions:

    To be quite honest I cant beleive this is so difficult out of the box. My problem is that I have 100gb of mail. I tried setting some settings in resolve.conf and lost the server (I didn't have permission so I temporarily changedpermission on etc, but could not put it back) 2 days that cost me.

    dig +nssearch 0.168.192.in-addr.arpa Does nothing. When I use my own IP, but muddle it up, remove last then use 3.2.1.in-addr.arpa I get some .ru servers and ip's. This doesn't really give me much of an idea how to get to the next level.

    For example, it might just be me, but the instructions for determining the network range and byte boundary are not that clear. Should I use 128/24 or will it depend on my settings? and if so, how do I find that. I dont even know if this will do anything, or even if my current ptr is wrong? Its says its correct, but it does not look mixed up like the ones in the example.

    Of course, I just end up with 100+ browser tabs open and no idea where I am. Plus, I suspect that I might have died of old age by the time this 'thread' is 'approved for public display', so I guess I am really just talking to myself? Anyone else do a lot of that? I didn't think so.

    Essentially, I am starting every few hours all over again with the general premise: CPanel wont send mail SMTP mail queued time out

    Another thread that tantilisingly details the issue but without a fix. Of course here the guy has no firewall issues:

    I tried traceroute -T alt1.gmail-smtp-in.l.google.com. -p 25 But unsurprisingly I dont have 'permission' to do that.

    Nor can I do telnet 65.55.37.120 25 Which is not surprising, what was I thinking imagining that would do anything, I probably dont even have telnet, whatever that is.

    SOLVED In short, I had to request that AWS lift restrictions on sending email: [QUOTE] Thank you for submitting your request to have the email sending limit removed from your account and/or for an rDNS update. We will require the following before this request can be processed. - A clear/detailed use-case for sending mail from EC2. - What type of configuration or setup have you implemented to prevent spam from originating from your EC2 resource?
    I did this and got this responce: [QUOTE] Hello, We approved your request for the removal of the EC2 email sending limitations on your Amazon Web Services account for the EU (London) region! If you requested removal of email sending limits on any other Amazon Elastic IPs, they've also been removed.
    To apply for this you need to log in on this page I think How do I remove the restriction on port 25 from my EC2 instance?

    Ha! It is amazing what typing out thoughts in a logical manner can do sometimes! I'm glad you were able to track this down, but it's very common for providers to block the email ports. If you need anything else, we're obviously a great sounding board for you :D
