comment Problem with Outlook sending HELO / EHLO
But the question is, why is Outlook sending HELO for one of the accounts (despite being configured to use authentication, which mandates use of EHLO)? Either that or something else is intercepting the connection and "downgrading" it.

comment Problem with Outlook sending HELO / EHLO
The poster said that EHLO does allow him to send. It's only when Outlook greets the server with HELO that it rejects the mail - reason being that one of those "other functions" is SMTP AUTH ;)

comment Problem with Outlook sending HELO / EHLO
Ah, sorry - had to re-read it as it sounds so bizarre. Did you see the HELO in server or client logs? If server then perhaps try enabling transport logging in Outlook (support.microsoft.com/kb/300479) to narrow down the source of your woes?

comment Why should I “outsource DNS”
+1, especially point 1 - better to ask why wouldn't I outsource DNS?

comment OpenSSH multiplexed connection unexpectedly closed
Nice, an OpenSSH feature I hadn't spotted before! Unfortunately I can't reproduce the issue, though - works fine here :) Does the -v flag of ssh give any more information?

comment Dedicated servers with DDOS protection
What kind of attack was this (e.g. which services was it directed at, how did it affect you/customers in practice, etc.)?

comment Is NAT completely transparent to a host?
Indeed - the whole point is that the host shouldn't notice, and most NAT implementations rewrite as much as possible to make this the case. There are protocols that do expose the IP and aren't as commonly rewritten (e.g. SIP, some P2P, anything encrypted) but I suspect this might be considered "server support" ;)

comment Is NAT completely transparent to a host?
I don't think this helps - it's for detecting NAT routers on your network that are "hiding" other hosts behind them, whereas the OP wants to know whether the host itself is behind NAT.

comment iptables — OK, **now** am I doing it right?
+1, especially if this is for something that matters. The tools will catch more corner cases that you may not even have considered when copy+pasting rules from SF questions. @womble: "...describe your desired policy and then have it translated into iptables rules" - are you talking about ServerFault here?

How does the number of apache child processes vary over the same period?
