osirusoft dopo un mese di test mi pare più che ok, dico bene?
invece spamcop troppo aggressiva, forse
e le altre??? voi avete esperienza diretta? che percentuale di spam beccano e quali errori sulla posta "regolare" avete riscontrato?
DESCRIPTION Relays.osirusoft.com is first and foremost, an automated system designed to protect its users from open relay UCE (ie spam sent through unsecured mail servers). However, it also includes the contents of several other DNSBL lists, including SPEWS, SpamSites.org and the Spamhaus SBL.
RESULT_CODE 127.0.0.2 # verified open relay
RESULT_CODE 127.0.0.4 # confirmed spam source
RESULT_CODE 127.0.0.6 # spamware developer/spamvertized site
RESULT_CODE 127.0.0.8 # insecure formmail.cgi
RESULT_CODE 127.0.0.9 # open proxy servers
DESCRIPTION The Open Relay DataBase is a non-profit organisation which stores a list of machines which are open (or insecure) SMTP relays. These relays are, or are likely to be, used as conduits for sending unsolicited bulk email.
NAME SpamCop Blocking List
DESCRIPTION An experimental service that lists those hosts that emit lots of spam relative to other types of email, based upon the spam reported using the main SpamCop service. The list will eventually be restricted but it can be freely used for now.
DESCRIPTION spambag.org is a personal list of networks whom the author believes actively or passively allow abusive or antisocial behavior. Examples of what he considers abusive or antisocial behavior are: spamming, mailbombing, mail server dictionary attacks, and web page E-mail address harvesting.
WEBSITE http://www.monkeys.com/anti-spam/filter ... mmail.html
DESCRIPTION This DNSBL service lists those hosts which run an insecure version of Matt's Formmail script (used on lots of websites) which spammers are abusing to send spam. If you get lots of spam that seems to come from a feedback form, this list could help you! NOTE: This service has recently changed its policy so that out-of-date entries are no longer removed. Thus is will become progressively more inaccurate as time goes by.
DESCRIPTION Lists various open proxies (insecure servers that can be used to access other servers and eventually send email) that are known to be used by spammers.
NAME Relay Stop List (RSL)
DESCRIPTION relays.visi.com lists those mailservers that have relayed third-party spam in the recent past. Such "open relays", once found by spammers, are often used frequently by the spammers until they are secured.
DESCRIPTION Arbitrary Blackhole List (or ABL) is a VERY AGGRESSIVE list of hosts known to be used by well-known spammers. It includes several popular hosts such as HotMail and Yahoo, so there is a high possibility it will mistake legitimate email for spam.
NAME Wirehub! Blackholes
DESCRIPTION This service lists the IP addresses of persistent spam sources, abusers scanning for open mail relays, abusers behind raped relays, open proxy servers, of spamvertizers and of spamvertized websites.
DESCRIPTION This lists parts if the Internet that are not compliant with RFC954, such as I.P. address with inaccurate or out-of-date information in IP whois records, and IP addresses which lack of any WHOIS service whatsoever. This list is not concerned with spam; however, the theory goes that those hosts not compliant with Internet protocols are more likely to facilitate other forms of network abuse (e.g. spam).
