Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : mails not been sent to hotmail

[koolnhot]

recently my mails are not been sent to hotmail and live users from the forum
I just checked by sending a test mail to my hotmail account but the mail wasn't recd. so I checked the mail queue manager in WHM and the hotmail related mails were not traced.

plz guide me on how I can overcome this problem, I can send mail to hotmail if they are bouncing but when I don't find in the queue , what can I mail about them , when they ask an error id

Hello,

Do you have an rDNS (reverse dns) setup on the mail server?

[koolnhot]

ya its been setup, I have done almost everything for mails to be sent as earlier we had problem with one of the mail provider

[TheServerExperts]

Can you check if you mail server is in a blacklist?

www.dnsbl.info

www.senderbase.org

[activelobby4u]

usual stuff..chek for spf, rdns and domainkeys for your domain

Also conform if the domain is blacklisted with hotmail, there should be a returned mail from hotmail, if they are being rejected

[sbunnithan]

Check for the mail logs using the command

tail -f /var/log/exim_mainlog
tail -f /var/log/exim_rejectlog

The mails send should get logged in it.

Once you get the message id you can see the status of that mail by using the command

exigrep <message id> /var/log/exim_mainlog
exigrep <message id> /var/log/exim_rejectlog

Try to rebuild the exim database.

/usr/sbin/exim_tidydb -t 1d /var/spool/exim retry
/usr/sbin/exim_tidydb -t 1d /var/spool/exim reject
/usr/sbin/exim_tidydb -t 1d /var/spool/exim wait-remote_smtp

You can check the details from here

I second this. SPF/DK/RDNS are going to be the major players here. A lot of ISP's will reject/queue mail if the RDNS isn't properly set up.

Did you have checked your ip is not been blacklisted in any database?
If it is then the mails sent to hotmail account might be going to the junk folder of the hotmail account.

I have checked in DSNBL its safe in all
senderbase doesn't show a proper report, reputation report is neutral

spf, rdns, domainkeys are already set

yah, I just tried to send a mail manually to hotmail and it got rejected, and this was the msg:

SMTP error from remote mail server after MAIL FROM:<webmaster@mysite.com> SIZE=2458:
host mx3.hotmail.com [65.55.37.104]: 550 SC-001 Mail rejected by Windows Live Hotmail for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems.

I am trying to send mail to SENDERID dept with SPF records

emails are sent properly to all other domains except hotmail and live, so I guess it has to do something with the hotmail only. My personal account is on live, so I think I have to contact them now via live account.

I got a doubt, I had sent mail to : check-auth@verifier.port25.com to verify authentication and I got these results:

Summary of Results
==========================================================
SPF check: pass
DomainKeys check: pass
DKIM check: neutral
Sender-ID check: pass
SpamAssassin check: ham

I don't see any where the meaning for ham to b listed in the mail in which the automated reply was recd
they had given only for following details:

"pass"
the message passed the authentication test.

"fail"
the message failed the authentication test.

"softfail"
the message failed the authentication test, and the authentication
method has either an explicit or implicit policy which doesn't require
successful authentication of all messages from that domain.

"neutral"
the authentication method completed without errors, but was unable
to reach either a positive or a negative result about the message.

"temperror"
a temporary (recoverable) error occurred attempting to authenticate
the sender; either the process couldn't be completed locally, or
there was a temporary failure retrieving data required for the
authentication. A later retry may produce a more final result.

"permerror"
a permanent (unrecoverable) error occurred attempting to
authenticate the sender; either the process couldn't be completed
locally, or there was a permanent failure retrieving data required
for the authentication.

Your ip address might blacklisted by hotmail due to spam issues.

[koolnhot]

my ip is safe in all other lists and I was able to send mails even before few weeks ago to hotmail, its just now the prob occurs

Microsoft, as I mentioned above, was collaborating in the DKIM. But they use their own technology, called SenderID. Sender ID is basically SPF with Microsoft's spices. SenderID is a caching system for SPF records. Thus you will find things a bit quicker if you e-mailed senderid@microsoft.com to inform them you changed your SPF record or created one. Then they will reload your domain's cache.
Read more at http://www.microsoft.com/senderid
Once again this means that Microsoft relies on SPF. After creating SPF record for the domain under investigation, e-mails started to appear in Hotmail's junk mail which isn't expected and is an indicator that there's something else to do.

Additionally, I found this:
http://windowslivehelp.com/community/t/25409.aspx

"...it appears that your domain is being affected by our automated spam filter. My co-moderator, Windows Live Jacqui F, has already escalated your concern to our Windows Live Hotmail Sender Support Team...."

Your domain/IP may have succumbed to an auto-ACL, which would require contacting MS/Live to have it corrected. You could also try configuring Exim to listen on a different IP if you have the resources and ability to make such a change. Be sure to make a backup of exim.conf if you intend to try this.

looks like missed spf and rdns for me
