I have grey listing running and it seems to work well stopping the bulk of spam. But I had one chap complaining last week that some one was emailing him and it was failing to get through. A quick log check showed
2009-06-04 12:29:10 [76405] H=vscano-b2.ucl.ac.uk [128.40.105.157]:47833 I=[94.76.221.176]:25 F=<[email protected]> temporarily rejected RCPT <[email protected]>: greylisted host 128.40.105.157 2009-06-04 12:29:10 [76405] H=vscano-b2.ucl.ac.uk [128.40.105.157]:47833 I=[94.76.221.176]:25 incomplete transaction (QUIT) from <[email protected]> 2009-06-05 16:19:50 [48875] H=vscano-a2.ucl.ac.uk [144.82.100.153]:64384 I=[94.76.221.176]:25 F=<[email protected]> temporarily rejected RCPT <[email protected]>: greylisted host 144.82.100.153 2009-06-05 16:19:50 [48875] H=vscano-a2.ucl.ac.uk [144.82.100.153]:64384 I=[94.76.221.176]:25 incomplete transaction (QUIT) from <[email protected]> So I guess there server just never retried after being grey listed at least not from the same host. Other than not greylisting I take it theres no way of avoiding the odd incident like this There email got returned with a 550 unable to relay error. I am no expert at this but I do try and get things right and avoid causing other people problems. I have since whitelisted them ( using postgrey by the way ) .
