II. what should we do, i already search this problem in google
http://www.google.com/#hl=en&q=cannot+send+yahoo+mail , and i guess its could be because the rdns
quoted from resource
http://help.yahoo.com/l/us/yahoo/mai...master-15.html :

Publish reverse DNS (PTR) records for your sending IPs. If there is no reverse DNS entry for your IP address, or if it looks like a dynamically-assigned IP instead of a static mail server, Yahoo! is more likely to downgrade its sending reputation.

The rDNS already setup
1.1.1.0 ns1.domain.com
1.1.1.1 ns2.domain.com
1.1.1.3 domain.com
Here is the name server, i only use 1 dedicated ip, it is 1.1.1.3 for domain.com, the other domains are shared :
1.1.1.0 (main shared IP) (shared IP for root) (nameserver ns1.domain.com)
1.1.1.1 (nameserver ns2.domain.com)
1.1.1.2
1.1.1.3 (dedicated to domain.com)
1.1.1.4
The hostname are server1.domain.com, there is no dns zone for server1.domain.com before, i already tried add that dns zone too before but still cant send email to yahoo.com, do you think maybe this is the problem, need to rdns server1.domain.com too?
III. below are working example sending email to gmail.com from domain.com, and from other domain domain2.com
still not working sending email to yahoo.com, it is no problem when still using previous server, previous server are not using rdns at all
- example 1, from
support@domain.com, using outlook express, the mailed-by information are from domain.com (ip 1.1.1.3 (dedicated to domain.com))
from domain.com <support@domain.com>
to
xxxxxxx@gmail.com
