There seems to have been a very long email delay of a day and a 
half at priceless for my invoice email:

Do you log mail connection attempts anywhere?

Actually, I'd looked at the log as I know that mail via A&A has a problem 
(sorry, should say "issues," the fudgy word of choice in our society these 
days) with greylisting, or my greylisting has a problem with A&A, and that 
can cause a day's delay. But there was nothing.

The first try appears to be at 22:32 when my mailserver told it to go 
away and then it tried again at 23:28.

The log below starts on 27th January:

I gave up on greylisting - Too many never came back. Blueyonder in 
particular.

Greylisting was the magic bullet for me.  If Blueyonder cannot handle a 5 
minute delay then they have problems that far exceed the problems of tiny 
me using greylisting.

I think mine was set at 10 minutes. A mail from BY would bounce off, 
they would not come back, I was logging everything so could see, and 
about three days later the sender would get a mail bounce of "retry 
limit exceeded" or similar. Of course I had no idea until a relative 
on BY contacted me. As I run a mail list that has BY members I thought
it best to turn off the greylisting - which as you say *does* work 
wonders. It roughly halved my spam. But as bogofilter catches it all 
anyway I just turned greylisting off.

I had some problem with hotmail trying only once when I began using 
greylisting but suspect that was a problem with particular servers as 
some connections were retried and delivered. That problem resolved 
itself before I'd added a net group for hotmail. At same time I'd 
noticed other reports of problems receiving email from hotmail.

Apart from that, greylisting has made by far the largest reduction in 
amount of unwanted email of any measure I've tried.

I don't have any regular contacts using blueyonder but a quick check of 
logs shows many unwanted emails from them and prior to greylisting it 
was probably isp to which I'd emailed most abuse reports.
