Mail arrives in SPAM on Yahoo

[alecksievici]

The problem is pretty simple: when i send an email from my server (from any domain) to yahoo, it gets flagged as spam. Any other server (gmail or any other free email provider) receives the mails in inbox.

Until a few days ago i thought this was becuase my ip wasn't properly configured by my internet provider (when looking up the hostname on my ip i was receiving blowfish.from.swordfish), but now it works ok.

I've set up my hostname and the hosts file to match the lookup, i edited postfix's main.cf to also match the lookup and still it doesn't work.

Could this be an issue from ispcp, my postfix configuration or just yahoo's problem?

PS: i used http://www.isp-control.net/documentation...l_problems and everything looks ok...

i really need help because it's driving me crazy :-W

please show:
postconf | grep "^my"
host your server
host your ip

using domain keys and/or spf records should help

Code:

postconf | grep "^my"
mydestination = $myhostname, $mydomain
mydomain = $myhostname
myhostname = mail.greenbit.ro
mynetworks = 127.0.0.1/32 80.96.56.98/32 192.168.0.1/32
mynetworks_style = host
myorigin = $myhostname

host mail.greenbit.ro
mail.greenbit.ro has address 80.96.56.98

host 80.96.56.98
98.56.96.80.in-addr.arpa is an alias for 98.64-127.56.96.80.in-addr.arpa.
98.64-127.56.96.80.in-addr.arpa domain name pointer mail.greenbit.ro.

using domain keys and/or spf records - about this i kinda don't know, but i assume i use spf records (default ispcp v1 - debian lenny) and i guess it's this thing: v=spf1 a mx ip4:80.96.56.98 ~all

Well, if you don't have at least a /24 prefix your provider most-likely does not delegete reverse dns to your nameservers. So I guess yes you have to call your ISP ;-))

oh well, lucky me...
at least could you tell me how those lines should look like, because i'm sure that the guys from my isp won't know what to do and how they should look like...

i guess they can't give me a /24 prefix...

in the rev zone 56.96.80.in-addr.arpa:

yeah thats a /26 prefix... delegate zones smaller than /24 is a dirty hack... (but not impossible...)

well, just called my isp, they registerd my complaint and now i have to wait.
and about that "dirty hack", it's their problem, they'll just have to fix it.
thanks for your help and as soon as they fix the problem i'll send a few mails to yahoo and see if it's working and i'll post here the results . again, thank you for your help.

dirty hack is just when they delegate prefixes smaller /24 to your ns... Just altering the ptr should be a task of 1 minute...
