Almost 30% of all net addresses in Belarus are blocked by anti-spam firms because of the amount of junk mail passing through them, says a report.
East European nations top the list of countries with the largest percentage of blacklisted net addresses, said security firm Cloudmark.
It said Belarus had become popular among spammers as other nations cracked down on junk-mail senders.
The US was still the single biggest source of spam, it said,
Belarus (27.4%), Romania (22.3%) and Russia (3%) filled the top three slots of a list of nations that have IP addresses known to be sources of spam, said Cloudmark researcher Andrew Conway.
Now, he said, data traffic from just over three million Belarusian IP addresses was being blocked in an attempt to stem the flood of junk mail passing through them — via redwolf.newsvine.com
