    It would appear there are still some things to be done, to finish setting up the Server properly.

    There are some serious problems as mentioned here.
    http://www.dnsreport.com/tools/dnsre...n=oservers.com

    This is probably why HotMail is not accepting eMail from your Server.
    http://www.dnsstuff.com/tools/ip4r.ch?ip=207.44.212.39

    HotMail and many others, require there be a Dedicated IP address either for the Server itself or the Domain name sending the eMail. An SPF record is highly advisable as well.

    You should get some quailified help, either from your DC or hire someone, for correcting the above. Time is of the essence for fixing the 'Open Relay" settings.

    Rob,

    All hotmail cares about is your IP being listed as a spam source and an SPF record. I have about 13 domains on one VPS and hotmail recieves all the email I send there.

    On a side note I also get errors on the same two black lists as can be seen here http://www.dnsstuff.com/tools/ip4r.ch?ip=217.36.122.213.

    Beg to differ with you, Paul.

    Many people have problems sending to, HotMail, Yahoo, etc., and this is an example of why.

    http://postmaster.info.aol.com/errors/421dnsnr.html

    Also includes a link so one can verify, if their rDNS / PTR record is setup correctly.

    No idea what errors you refer to at dnsstuff, although, your link does show the PTR record is not setup correctly.

    Hi Rob,

    The PTR on that IP is not set up because BT refuse to set one up for us. That domain is served by exchange server in the office.

    One of the other domains on that VPS is dephenom.net.

    Both of the domains are able to send to most of the free providers but I know the first domain has problems with AOL that link has given me the reason.

    hotmail is very picky about proper forward and reverse DNS matching, smtp greeting being the same, SPF record, etc...They do have a support team that can assist you and tell you why you might be getting blocked.

    Can you telnet to one of their mta's on port 25 from your mail server?

    Contact Hotmail directly and find out if your IP has ben hardcoded into their block list, if so get a new IP.

    My server can't send to hotmail also, it sends but it doesn't show up in inbox or junk. SPF and rdns has been set up, no filters are in place on the hotmail account.

    You really need to fix up your domain so that it gets a clean dns report:

    http://www.dnsreport.com/tools/dnsre...n=oservers.com

    Right now, the mail server seems to be an open relay. No wonder other mail servers don't want to accept mail from you. You also need an rDNS for mail.oservers.com.

    After you get the dns report to be clean, then you can start contacting hotmail to see if they will allow mail from your server.

    But, close that open relay asap! Posting here has just pointed this out and some spammer might start relaying mail through your server and more mail servers might start to reject email from you.

    A) See if any of your IPs are Blacklisted.
    http://www.dnsstuff.com/tools/ip4r.ch?ip=

    B) What error msg. if any, do you get when sending the eMail?

    Also, login to your Server and tail Exim when you send an eMail, to verify it was sent.
    tail -f /var/log/exim_mainlog << if using WHM/Cpanel for example

    the IP is not blacklisted and the email did indeed go through because if I add the domain to the safelist on hotmail, it receives the mail. This hotmail has no domains on the blocklist.

    I have the same problem actually, SPF & rdns are set. But it doesnt arrive in my hotmail inbox.

    Here is the dns report:
    http://www.dnsreport.com/tools/dnsre...omain=groov.nl

    SPF check:

    Contact them, you'll loop in circles, but you'll get the story. In a few exchanged messages with them, you'll be instructed to join some programs of theirs (!). The filter is obviously biased and operates in a dubious manner (and secret one - you won't get ANY concrete info), doesn't deliver mails from Squirrel, from the server with perfect DNS and SPF, or puts them to Junk at best, even if they contain a single sentence in the message body.

    Their servers accept mails with 250 OK, but later either discard them in silence or put them to Junk. No information about the reasons is given. Only theoretical SPF instructions, recommendations to visit some URLs of theirs (with more theory and generally useless legal babble) and repetitive suggestions to join some organizations/programs of theirs.

    Been trying to progress for three days already, no results yet.

    I'll refrain from commenting this, those who have already experienced this know what I mean.

    Oh yes, and you'll be presented with a 21-item questionnaire to fill and mail back.

    Can you send emails to hotmail.com now? And is that questionnaire the same as on http://postmaster.hotmail.com ?

    Yes, same questionnaire. Can we send mail? So-so. Under testing, still not confirmed, but there were problems today as well.

    Went to my Hotmail inbox a couple of times to see if the testing mail I have sent from one of the servers has arrived. Saw two test mails I sent to myself from one client's Squirrel, but mail sent from another testing server hasn't arrived.

    But few mails with subjects like 'EUROPEAN PRIZE AWARD DEPT' (phishing - any decent antispam engine can easily be trained to recognize those, especially on such huge relays, where any training/retraining can be done on millions of samples - with good samples and proper training/retraining, CRM114's author claims to have reached the accuracy of 99.984%), stock spam (image only with the hyperlink) and online poker spam (image only with the hyperlink) were neatly delivered to my mailbox, not even dumped to Junk.

    Maybe we can tell our clients to compose their mails in Gimp or Photoshop

    Naturally, mails sent with fake From: addresses pass their 'smart' filter, while legitimate, one-liner mails end up discarded silently or bunked to junk. How is that triggered?

    For that casino piece of spam, a small yellow square appeared above the message:

    'The sender of this message, XXX@hotmail.com, could not be verified by Sender ID. Learn more about Sender ID.' I couldn't get that square in those zillion test mails sent while probing.

    Personally, I think this is what it is about:

    http://www.senderscorecertified.com/fees.html

    and this:

    http://www.emailauthentication.org/

    While playing/experimenting with CRM114, I have found a link to Camram... and found this there:

    http://www.camram.org/auth-dangers

    An opinion definitely worth thinking about.
