Hotmail rejecting my sendmail configuration
Hotmail rejects the emails I am sending using sendmail. They don't even become spam emails. They just never get there. Gmail gets them, and yahoo mail gets them as spam.
There must be something wrong with the sendmail.mc file.
If you know more about it than I do, please check it out (assuming you're masochistic enough to enjoy looking at a sendmail.mc file
)

I didn't look at your config, but if you are on that server (either ssh or local), do a telnet session to yahoo and hotmail and try to send a legitimate email telnet email - Google Search
see if either give any errors. you might also sign up for an @aol.com account and try to send there. aol tends to give pretty good postmaster errors.
when I had this problem (using postfix) it was because the ip address that I was sending email from didn't have an approprate ptr record. which is usually the case for spammers so it gets tagged/treated as spam.
Ip Tools, DNS tools, internet tools, WHOIS, traceroute, ping, domain name tools
go there and try to look up your info
as much as I like to bag on aol, they do a good job of providing postmaster help
Postmaster.Info : Troubleshooting E-mail Delivery
(even though you didn't report aol troubles
)
oh, and check your logs, they may give some insight

You can't send email to hotmail without signing up to some special thing microsoft has where you give them a bunch of personal and server details...
However, you can get around it by relaying you mail through a server that hotmail does accept mail from (your ISP's mail server should do the trick).
Add this to the end of your sendmail.mc:
change 'your.isps.mail.server' to the name of the server you'll be relaying through.Code:define(`SMART_HOST',`your.isps.mail.server')

not sure how true that is. my company has never done that with hotmail and we can send mail to them just fine. hotmail and a lot of others just require valid reverse records. not having a valid reverse record probably means you are on dhcp and not static and probably means you are a spammer.

the big sites can be more demanding on authentication.
I would look first in my bind/dns files or check with my host about my "PTR" records specially regarding my mail server...the ptr is like the reverse of what you normally do with website names.
it looks up th ip and checks that the nservers are in sync with the website name..
like a double look up
you got them wrong and it is a good immediate flag
