    Hey Guys,

    FireFold emails keeps getting marked as spam. We sent out easily 20k+ a month. Just recently seems we've had to fight 'anti' spam features such as Barracuda.

    What can be done? Can you pay companies to get white listed? etc etc.

    Thanks in advance.

    If you're getting marked as spam, you should contact whoever whomever is marking you as a spam mail. Either the host, or the person who got the email classified as spam, should be able to give you the headers of the email, and perhaps it'll show a little more as to why you're getting flagged as spam.

    The best choice would be to contact the place where you're getting flagged as spam, so that they can tell you if you're not meeting a certain criteria. For the most parts, anti-spam software adds up points which leads them to believe if you're spam or not.

    For example, if you do not have MX records properly set up, it's 20 points. If you don't have a reverse dns look up, that's another 20 points. If you're from Africa (or another country known for spamming) it could count as 30 points. Then if you make it over 60 points (or whatever it's set up as server side) you'll be marked as spam. If you get a lot of points, your email might just get blocked from server, and not allowed to send to that server.

    I hope all that made sense, and it is basically going to come down to you speaking with whomever blocked you (not necesarily Barracuda, but whoever is hosting the mail server as it's their settings.),

    Since it's an automated system how could I tell? FireFold only emails a person when they place an order or add themselves to one our email lists. So it's not like we are shooting random emails out to anyone.

    Yea, since your mail server's IP is listed on the Spamhaus XBL, you will need to contact your mail server host, so that they can get the mail server off the list. This list basically saves IP that are known to spam or do anything of that sort, and you're unlucky enough to be in the same server as either someone else that spams, or could be you that listed it.

    Your best bet is to contact your mail server provider, and ask them to please contact Spamhaus. In the case that you're getting blocked by Hotmail, it'd probably be a hard task, since they're not very easy to get a hold of, and not very friendly towards getting a server whitelisted.

    1) You'll probably need to get a dedicated IP for sending mail if you're going to send at any volume; pretty much all the major operators calculate some sort of "score" based on your IP's record of delivery. The "score" includes: how many mails you send, how many are to "real" recipients (not deactivated users/nonexistent accounts), how many people complain about your mail, whether you not you hit any spam "trap" accounts, etc.

    2) A valid SPF record (http://openspf.org) is also basically required. You can also use DomainKeys or DKIM (http://dkim.org/) to improve your deliverability to Yahoo! accounts. If you're sending invites or other user-generated mail, read this in particular: http://www.openspf.org/Best_Practices/Webgenerated

    3) Process your bounces. If you keep sending mail to a deactivated account, this looks very bad. Microsoft in particular has been super-aggressive about this. Set up a script that listens to incoming mail to your postmaster account.

    4) Enroll in Microsoft's JMRP and SNDS programs (http://postmaster.msn.com/) -- there's a bunch of other stuff about Microsoft's practices there, too. SNDS lets you know how your mail is treated by the Hotmail servers, but you need to send at least 100 mails on any given day to get the data. JMRP forwards complaints from Hotmail users to you so that you can unsubscribe them.

    5) This is the only guaranteed way to get into Hotmail --If you're serious about your site and you can cough up $400 to apply (and $1000 a year), Microsoft maintains a whitelist through a company called ReturnPath (http://returnpath.net) and a program called Sender Score Certified, which has some pretty intense requirements. The process can take a really long time, but we just went through it, and it's not too bad once you get the process going. (http://www.senderscorecertified.com/)

    6) It helps to have an unsubscribe link and a postal address at the bottom of your email. Hasn't really been confirmed one way or another, but it seems to help at least with yahoo.

    Just get a new IP block for your shit.

    Also i suggest using the marketing tool "Campaign Enterprise"

    Real good tool. We sent out about 200k with that alone in a month.

    Your IP could be blocklisted. Run it through Spam Assassin and see what the deal is.

    We use a dedicated ESP at work to send out 100k+ emails a week (crossing several markets). All of what Tony Stark said is 100%.

    If you look at going for a dedicated ESP they should be able to help you with diagnosing any problems and help you resolve them. A few of our domains got hit by gmail, but after we corrected the problems, no more issues.

    We found the biggest problem was people are quick to push the "Flag As Spam" as a method to unsubscribe. If this happens enough, you'll get flagged. Make it simple to unsubscribe. There are sites where you have to log into an account you created X years ago (which you've forgotten) just to unsubscribe. Marking it as spam is easy and will filter all new future email from that sender.

    Taldir,

    Here are some sites to check your server's (or mail servers) IP address to check and see if it's being reported.

    http://www.dnsbl.info/advanced.asp
    http://openrbl.org/

    Also, make sure you have SPF and Domain Key setup in your Zone File. This will help with the Spam scoring against Spamhaus, amongst other Black Listing directories.

    I show your mail server IP being blocked at quite a few RBL's. I'm including info to help remove those listings.

    Blocklisted at bl.spamcop.net - Blocked - see http://www.spamcop.net/bl.shtml?166.82.119.10
    Blocklisted at psbl.surriel.com - Listed in PSBL, see http://psbl.surriel.com/listing?ip=166.82.119.10
    Blocklisted at virbl.dnsbl.bit.nl - See: http://virbl.bit.nl/lookup/index.php?ip=166.82.119.10
    Blocklisted at bl.spamcop.net - http://www.spamcop.net/w3m?action=dispute;ip=166.82.119.10
    Blocklisted at HOSTKARMA - http://ipadmin.junkemailfilter.com/remove.php?ip=166.82.119.10

    I also found this:
    * DNS error: 166.82.119.10 is Email.FireFold.net but Email.FireFold.net is 166.82.231.219 instead of 166.82.119.10
    This means you need to fix your rDNS for 166.82.119.10, as it's showing the same as 166.82.119.10


    Hope this helps! PM me if you wish, I'll give you my personal contact info, I can help get some of this stuff cleared for ya if you like.
