RE: yahoo n hotmail not accepting mail from one domain

The Yahoo and Hotmail mail servers are so diffferent from the rest of the world's that one can but wonder where to search for the right answer. But, if you are convinced that your DNS records are as they should I would approach Yahoo and Hotmail about the issue. Maybe they are blocking (from whatever reason) emails from your domain..?

Your problem lies with the configuration of your domain within bind.


Please refer to http://www.linuxjournal.com/node/1000079

Technically, you can send email from any machine, but the larger email providers such as Yahoo or Hotmail now rely heavily on SPF records to make sure the sending domain has an SPF record. If email arrives from a machine that is not listed in the SPF record, then an MTA could classify you mail as spam.

A wizard exists for creating SPF records at http://www.openspf.org/wizard.html?mydomain=&x=26&y=8. We used this wizard to create an SPF record for example.org, and added it to our zone file:

example.org. TXT "v=spf1 a mx ~all"
server1.example.org. TXT "v=spf1 a -all"

Subject: yahoo n hotmail not accepting mail from one domain

Dear ALL,

I dont know really if my problem is DNS problem or MTA problem


i have a redhat server 9 as my primary name server running the following

bind-9.2.1-9
sendmail-8.12.5-7
domain name = kmun.gov.kw
ip address = xx.xx.xx.1
mx record for kmun.gov.kw= xx.xx.xx.1

this server also host another domain baladia.gov.kw

i also have a secondary DNS running

bind-9.2.1-9
ip address = xx.xx.xx.2

all has been running perfectly well for long time

recently we decide to have a mail server for our other domain

baladia.gov.kw

installed sendmail (same version )on our secondary DNS server that is
xx.xx.xx.2 and set up a mx record

xx.xx.xx.2

and everythin is working fine..
i can send send mails from my new domain that is baladia.gov.kw and also all mail send to any user@xxxxxxxxxxxxxx is received perfectly OK

but i have found that whenever i send mail to yahoo or hotmail the mail gets delivered to junk mail folder and not to inbox
but mails sent from my earlier domain kmun.gov.kw are delivered correctly to the inbox

both domain configs are the same n the zone files are correct and sendmail is configured likewise

aslo i have checked if the servers are in spam n infact they r not

so jus wondering why mails sent from my kmun.gov.kw get delivered to yahoo and hotmail correctly and blaladia.gov.kw do NOT.


really appreciate you help


Thanks and regards


simon
