    Spam and Colocation

    Hi all,

    I am thinking about where to colo my shiny new servers. There are the questions of bandwidth quality, cost, and support level, which I think I have sorted out. But then there is spam... why does this matter? Well, maybe it doesn't, that is what I need you help on

    My understanding is that when I am assigned IP addresses (I need 3 to start out) that they will of course belong to a block of IP addresses. And that that block of IP addresses may or may not be 'blacklisted' by anti-spam organizations. And that if they are on the blacklist then it will hard for me to get my IP addresses off of the lists. And therefore it will be hard for me to send email to people from those IP addresses.

    Is this correct?

    Also, do some colocation facilities prosecute spammers more than others, and does it make it easier to stay off the black lists?

    Any insight deeply appreciated!
    Scott

    As far as I know, only the IP where spam emails are sent out will be blacklisted.

    Here is a link...

    Thanks for the response. I did a search, and this is a good link???

    I think it says that the whole netblock is put on the blacklist???

    Thanks again for any insight,
    Scott

    Spam

    The reason ISPs care about SPAM it is typically against the AUPs of their bw providers to send out SPAM. The ISPs want/need to stay in good standing with their bandwidth providers.

    I don't know of any ISPs who "prosecute" spammers, they typically just cancel your account and violators typically loose any deposits and may be liable for the remainder of their contract.

    IMO, the $ a spammer pays is not worth the headaches that come from the bw providers and SpamCop.

    A quick way to check many blackhole databases is SamSpade:

    http://samspade.org/t/rbl
    http://samspade.org/t/rbl?a=webhostingtalk.com

    It checks Checking VISI.com Relay Stop List (RSL), Osirus Relays List (OSIRUS), Dorkslayers ORBS-clone (DORKS), Dorkslayers Zero Tolerance List (DORKZTL), Open Relay Database (ORDB), Arbitrary Blackhole List (ABL), DevNull (DEVNULL), Five Ten (FIVETEN), ORBZ Inputs (ORBZIN), ORBZ Outputs (ORBZOUT), SpamCop Blacklist (SPAMCOP), Intersil (INTERSIL), Compunet (COMPU), FloNetworks List (FLOWGO), Summit Blocking List (SBL), Spam Prevention Early Warning System (SPEWS), Blitzed Open Proxy Monitor (BOPM), and Spamhaus Block List (SBL).

    SamSpade is very useful, never leave home without it.

    Depends on the RBL - some block the whole network. see www.openrbl.org for all the current info.
    A lot depends on the provider. They should be listed with a current abuse mailbox w/ ARIN and and have zero tolerance for spammers for the very reasons mentioned here.

    Ok, since they do blacklist whole IP blocks do I need to:

    1. Find an ISP who cancels customers who spam?
    2. Get my own listing with ARIN so taht I will be perceived by everyone as not being associated with my block? Remember I will only have 3 IP addressses...

    Thanks again for any help,
    Scott

    You should not be concerned with this. This should be your providers problem to deal with not yours. A vast majority of the ips providers assign you are quite clean.

    If you are really concerned....

    Ask your provider to give you one of the IPs you will be assigned in advance and check it against the lists. Once you have and it is all clear, unless you send out SPAM yourself, you will be good to go. :-)

    Of course he should

    Ys, but if customers do not complain, the provider will have no incentive to boot their spammers and get their netblocks de-listed.

    I see no reason why it shouldn't be grounds for contract cancellation. If he can't send mail, why colo there?
