Thanks all for the feedback,

Same as you Andris, nobody is complaining, I was just putting my nose in my 
stats of time messages spend in queues and the difference with other domains 
struck me.

Subject: Re: [mailop] 20 seconds connection delay

On our case I think we have always had a 20 sec delay between *every* SMTP 
command when sending to Rambler, so every message takes at least 60 seconds to 
deliver. Haven't been a problem, even though messages to Rambler might pile up 
temporarily if there's lot of trafic to this destination. Not enough traffic 
that anyone would complain, enough for us to notice.

As I saw a bunch of joomla sites with unprotected (or poorly protected)
account registration pages being abused to try and bomb<>
addresses this morning this theory sounds valid...
