After disabling relays.osirusoft.com (DNSRBL), I was checking my mail logs and found hundreds of: wahoo postfix/smtpd[21655]: connect from unknown[61.248.137.183] wahoo postfix/smtpd[21655]: disconnect from unknown[61.248.137.183] Parsing input: 61.248.137.183 host 61.248.137.183 (getting name) no name Reporting addresses: spamrelay@certcc.or.kr postmaster@shinbiro.com abuse@shinbiro.com and [pls forgive long lines] wahoo postfix/smtpd[7629]: connect from CPE0050f2c347af-CM400026310183.cpe.net.cable.rogers.com[65.48.226.202] wahoo postfix/smtpd[7629]: disconnect from CPE0050f2c347af-CM400026310183.cpe.net.cable.rogers.com[65.48.226.202] and several others over the last 4/5 days. The first listed, 61.248.137.183, tried for 3 solid hours 3 and 4 times per second. Are they trying to relay mail thru me, or what ??? tks, -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org
