Server Bouncing Emails To Hotmail, MSN And Others
Aug 6, 2007
I have one of our servers that is bouncing all sent emails to hotmail, MSN and some others. The emails often come back saying they are bounced as SPAM.
There were SPAM issues on this particular server at one point, but have since been corrected one we tightened it up.
Now, how can I fix this? Can I change the servers hostname? Are they rejecting by hostname, or by IP?
And do I need to just contact each provider and try to get off their blacklist?

While I am used to reselling and domain registration stuff, I am totally new to DNS stuff..I tried many searches and readings without hope.
that's why I need your help.
We have a problem that makes both incoming and outgoing emails from our website's email server not going or received, without any failure message or error message on both sides: the sender and receiver.
We talked to our webhosting company- they do not own, but host on a dedicated provided by Iweb in Canada - and they told us a quick solution for this:
To buy a private IP address, therefore our websites with them will not get blocked as spammy IP, setting us away from the dozens of sites they have on the same server IP (as domaintools reverse IP reported: xx other sites hosted on this server).
The company I work for agreed on this solution immediately as we are loosing customers for this problem.
They charged us 8$ a month for this "private ip".
We had the same problem for another day after their solution, when I checked domaintools, I found our websites are still on the same IP of the company. I called them, and the Admin there told me: it's a hidden CNAME setting that is not shown to public because it's "private" and the delay happenned because we had to contact Hotmail staff and wait for their reply to include it in their safe list, but others as Gmail and Yahoo do not require contacting them and will go through automatically."
My question is:
- What is Private IP/ Private DNS?
- Why and how it is used to prevent false blocking/bouncing?
- Does that mean they had to sell it to every domain, while their IP is not on blacklists (I checked it).
- Is Private IP just an internal setting or it has to be bought from a large ISP
like regular/public IPs? and if just some settings, is this price fair? we pay 120$ annually for hosting one site with them.
- They told us they put our other two sites on theis same new private IP. How can this be possible?
- I cannot understand: Hotmail can prevent our emails from reaching inboxes, but can it also prevent its users emails from reaching us?? Is this issue a Private-IP related??
- What do you think the real problem is, and what advice(s) should I follow to have our emails going and coming smoothly in the future?
Note: We don't send unsolicited emails ever. We only have a 1500-member mailinglist that we send a newsletter to, once every few months.
Our daily email traffic is about 10 to 20 messages in and out.

I have 2 cPanel servers with normal decent setups, and until today, HOTMAIL/LIVE is not accepting my e-mails.
There is no problem with GMAIL & YAHOO, btw.
When I mentioned not accepting my e-mails means it will always appear inside the Junk box instead of Inbox (for every domains in both servers)
I've tried to contact Microsoft support many times but they keep repeating the same thing. I've tried everything including make sure that my IP reputation is clean, and having domain keys.
I need some advise from you guys out there that has this issue before and start from sketch, what do I need to do to identify what Microsoft servers actually want from me?
Here's their 'robotic' respond.
1) Make sure that you have SPF/SIDF records in place. You
can go to [url]
for more information on this.
2) Clean up your lists. Remove those who do not want to
receive the emails. Make the unsubscribe process more visible. Hotmail
also has a sender complaint feedback loop program called the Junk Email
Reporting Program (JMRP). Enrollment in this free program will benefit
you as a sender as it will keep your email lists updated and populated
with interested Windows Live Hotmail Customers. This program will help
you to remove those Windows Live Hotmail Customers who do not want to
receive emails from your company. If you are interested in joining this
program, please visit
[url
_options_form_byemail&ct=eformts
3) Ensure that there is not anything technically wrong with
your MTA. Are your DNS records updated, are you transmitting data upon
making the SMTP connection, and is the problem isolated to any specific
machines? Do your SMTP logs show any failures?
4) Segment your mailing infrastructure by IP. Marketing
email, transactional corporate email, "forward to a friend" email and
signup emails should be sent from different IP's. This will help to
identify what types of messages are being flagged by Hotmail customers.
5) Strengthen the sign up process. Confirm that you are
using a double-opt-in sign up process. This will not help in removing
existing Hotmail customers from your email lists, but it will confirm
the authenticity of those who sign-up for your email campaigns and
newsletters.
6) If you have any feedback loops setup with other ISPs,
you should look for trends to try to determine possible causes - a new
data source? New advertisement? Maybe folks signing up do not recognize
the mail?
7) Clearly mark your emails so that Hotmail customers are
able to identify quickly and easily that they requested emails from your
service.
8) Do some analysis on the data regarding complaints - look
at Hotmail customers who have never clicked, opened, responded or
bounced in any way. These poor performers could contain many bad
addresses.
9) Evaluate the frequency of your mailings. Are you making
your mailings less relevant and welcome by sending too many emails?
10) Enroll in the Sender Score program. This is the only white
list that Hotmail uses. It is owned and operated by Return Path. You can
find information about this program at
[url
11) Please visit [url]
to verify that your IP is not being listed
on any third party block lists.
12) We also recommend that you take advantage of the following
email delivery consulting companies who participate in the Messaging
Anti-Abuse Working Group [url]
), and the Authentication and Online Trust
Alliance [url]

The issue is that a lot of my emails seem to be bouncing back at the moment with the subject 'Subject: Warning: could not send message for past 1 day'
Could anyone explain why this might be the case? I've had a look online and the only thing I can think it might be is that my email address has been gray listed. To solve this it was recommended to use a SPF Record.
I did not really want to start messing around with my DNS before I could get some confirmation that this is the case. Though if there is another explaination please can you let m know.
The emails that I have sent have all had pdf's attached to them.

I cannot figure this out.. I have tried EVERYTHING..
I am running a php script using the mail() function and sending an email..
I have had reverse dns point to the domain
I set an SPF record
My IP is not blacklisted.. I have had the dedicated server for 2 years now also
I modified a few things in the sendmail files.. I am stuck..
I am running freeBSD.. My buddy has his server set up with all of the same sendmail settings being the same.. and his emails don't get flagged..

I own my domain [url] and have a reseller plan on a shared host [url]I have the DNS on godaddy pointed to the nameservers of reyox and on the Cpanel of my domain at reyox I have a forwarding account [url]set to forward to my gmail account.
To the best of my knowledge this has worked flawlessly for years but recently I have been starting to not receive emails from people. I found out when I wasn't getting replies I had been expecting and when I inquired or called the people instead they told me that hey replied... it's been happening over and over again lately.
When I asked my host last week they replied: "We did clear up some mail issues last night, some issues with the queue processing."
However after that it kept happening and now I am at a loss.
I don't know what's wrong nor how to troubleshoot it... It happened with people that are on all sorts of domains (gmail, aol, personal domains etc) and it happens sporadically...
It's really frustrating because I don't know what else I am not getting considering that every other day I find out about an expected email I didn't get.
The werid thing is that none of the senders whose emails got lost reported that they received a bounce issue...
how I can address this in terms of troubleshooting it and finding a solution?
Is there some sort of email monitoring services like there are site uptime monitoring services?

I ran the script in KB article 123160 [1] to disable SSLv3 and avoid the POODLE vulnerability, but I recently discovered that this has caused all inbound emails to bounce. The bounce message says, "TLS Negotiation failed."
Here is Plesk version information:
# cat /usr/local/psa/version
11.5.30 CentOS 5 115140407.17
# cat /root/.autoinstaller/microupdates.xml

I tried to send an email to Hotmail.com and I get error messages. However, I can send an email to another email address that forwards to hotmail and it arrives correctly.
When sending via SquirrelMail I get:

I run a dating site, but for some reason hotmail is rejecting certain emails.
When a user receives a message on my site, they get a notification by email to come check their message on the site. This part works, even with hotmail.
However, when a NEW user registers on the site with hotmail, they aren't
getting the confirmation email they would normally get, and as a result they can't join the site. Other email providers get this confirmation email, but not hotmail.

I have problems sending emails from my VPS to Hotmail and Gmail email accounts. This is a new VPS with some new websites so they are not blacklisted for spam or anything like that.
After users register at my website they receive a welcome email, but with Hotmail/Gmail accounts they end up by default in the spam/junkfolder.
I also have a refer-a-friend and a forgot password form -> with gmail users they both end up in the spamfolder, with hotmail users they both do not show up at all!
I read somewhere that editing the DNS zone could solve this problem with adding a SPF record (see also [url]).
I have added the most common SPF record "v=spf1 a ~all" as TXT record type but after a few days nothing has changed.
so all email send from the VPS to Hotmail/Gmail email accounts will directly be send into the inbox.

Testing out Clientexec, and every time a welcome email is supposed to be sent, it's not.
So i set up a SPF record for the domain, and it started sending that email. However, when checking the hotmail it's tagged as "phishing scam".

I'm in the process of trying to contact Hotmail. I thought it was an SPF issue but that did not fix it. I then thought rDNS, but on an old server the rDNS also pointed to the DC and not to the server hostname and it worked fine. I'm going ahead to fix the rDNS, but I'm not sure that it will fix this.
Anyway, does anyone know the solution here by chance?
Here's the error message (a 550):
xxxxxxxxxxxx@hotmail.com
SMTP error from remote mail server after MAIL FROM:<denver@higherpurposes.com> SIZE=1922:
host mx2.hotmail.com [65.54.245.40]: 550 Your e-mail was rejected for policy reasons on this gateway. Reasons for rejection may be related to content such as obscene language, graphics, or spam-like characteristics (or) other reputation problems.

On the main mail server I run from my site I have being receiving a lot of issues when trying to send mail to hotmail. I do not receive any error messages, the mail is just never received it is filtered out(it does not even show up in the spam filter). I am not a spammer and have never been. My IP and domain check out fine when I put them through spam databases. So is there some trick to getting your mail accepted?

All messages sent by my mail queue in cPanel are being blocked by Hotmail and the British ISP Blueyonder.
It only affects these two mail-companies.

I'm on CentOS 4.4, webmin, LAMP, OpenSSH and ProFTPD server.
But what I'm wondering is how to look at my off network backup space.
I can only access my backup space through the DC network/my own server. So I need some kind of way to bounce a GUI ftp connection off the server - which would allow me to look at the files...
I know I can use rsync for backing up and restoring. But the way I understand rsync I need to know exactly what I am to move, as it operates on an exact command.
