Small emails being delayed

It looks like small emails (a few lines) are being delayed by several hours whilst larger emails (around a page) go through relatively quickly.
I don't know what is causing this. At the beginning I was wondering if the system was overloaded (I was not getting emails I was expecting) but in fact, after a number of test using external and internal email accounts, I realised that the size of the message played a critical role in determining if I get the email or not.
I am convinced I will get the other emails tomorrow morning but still, this is really quite strange and not ideal IMHO

Are the emails being sent via relay.plus.net and where are they being sent to?

Note however that today it does not seem to be affected by the size of the message (I suspect in the end what mattered was which relay took responsability for transmitting the message).

It's not helping that some of the servers have a timestamp that's out by an hour (there's a task with our ops team to fix this).

I suspect some of these delays could be "normal" (machine overloaded for some reason). Now looking at the statistics panel it is very difficult to say because we don't know how many message per hours these machines are processing.
So I wonder if it would not be an idea to try and express the MX statistics in terms of expected delay for incoming and outgoing MX traffic.
I know this will only give an average idea as typically this is influenced by "is the machine at the other end responding?" but at least it would be better than "MX queue = 1k" which to me does not mean a lot...
