comment postfix mails (works) to all but my domain on debian
@HBrujn In what way does it not answer the question ? I would have throught it a direct answe to the question " I have a feeling that if I change the domain of the machine to something other than mine (and that is OK with me) it will start to work fine. I have tried doing this but think that I missed one. " - ie I'm asserting that this setting in his config is incorrect and fixing that will fix his problem.

comment Exchange with Postfix MX for technical accounts in same DOMAIN
Don't do this. Even if it is technically possible you are making a world of pain for yourself whenever something needs to be updated or goes wrong.

comment SSH Negotiation Failing To some sites
I've found a workaround - by specifying MACs=hmac-md5 in /etc/ssh/ssh_config or passing it as a parameter with -o lets me in, however I really want to know WHY this has suddenly become a requirement - and why it is only a requirement across the VPN.

comment Changing an `A` record to a `CNAME` without downtime
If you were to shift your domain to another registrar, I would imagine you would not have any downtime as cached information would go to your old provider and new information to your new one. Once everything is shifted across you could just remove your domain from your old provider. Your current provider does not sound "fit for purpose" for you anyway.

comment Changing an `A` record to a `CNAME` without downtime
I don't see why it should result in downtime - save for the actual tiny amount of time the system does not have an A record or a CNAME. I agree with @Wesley - but the alternative might be to set up on a new DNS provider, then shift your domain name to them. [Not what I would do, but I control my own nameservers ]

comment Iptables: Filtering string encrypted by ssl
I don't see how PFS does anything if you are, in effect, performing a man in the middle attack in realtime, so I don't think this is correct. PFS is, I believe, used to ensure that if the private key of a session is compromised at some point after the communication it can't be used to decrypt the communication. Certainly PFS does not prevent MITM attacks. see the section at "Limits of forward Secrecy" at randomoracle.wordpress.com/2013/10/14/… also the second post at sla.ckers.org/forum/read.php?6,7024
