[EMAIL] Securing EXIM and Spam Issue

I've recently have a lot of my emails from my domains doing to the SPAM folders of some mail clients like Yahoo! and MSN's Hotmail. I've verified this with different language to see if it might of been something specific that might of triggered this.
I've check the RBL lists and my IP for my server does not show any blacklisting or the like.

It bothers me because I have around 10 domains that serve specific purposes and rarely send mass emails. I do not sell products or solicit anything.

I've also been wanting t secure EXIM and forbid unauthorized use of SMTP since my logs show a lot of attempts to deliver mail using my server.

TIA.

Re: [EMAIL] Securing EXIM and Spam Issue

I think the problem with some of these mail services like Yahoo! is that the I'm sending mail using my dedicated server with EXIM setup to send through let say, server.maindomain.com, and I'm sending mail with anotherdomainsontheserver.com and I think the client is thinking I'm just using the maindomain.com as a relayer for spamming.

But I'm not sure that can be change right?
Sending emails using any domain through nobody, mailman, sendmail uses EXIM and SMTP through the maindomain.com no matter what?

So its there a way to auth or give an indication I'm authorized to send mail using this server?

2ND EDIT
********************************************

I've added DomainKeys to the domain in question which was having that particular problem, and it still fails the Yahoo! Spam Folder test. DomainKeys on the headers look fine, it passes the DK test and shows Auth with DK was made correctly.

I'll test with Hotmail to see if its maybe the lack of SSL or something else..

Thanks for at least reading..

3RD EDIT
*************************************

I've added SPF to the domain. Checks out fine with the SPF checks at skylist.net

MAIL FROM: totc@domain.com

PRA: totc@domain.com

SPF-Record-Classic: v=spf1 a mx ip4:x.x.x.x ?all

SPF-Record-MFROM Scope: v=spf1 a mx ip4:x.x.x.x ?all

SPF-Record-PRA Scope: v=spf1 a mx ip4:x.x.x.x ?all

SPF-Method Result: pass(domain.com: domain of
domain.com designates x.x.x.x as permitted sender)

SenderID-MFROM-Method Result: pass(domain.com: domain of
domain.com designates x.x.x.x as permitted sender)

SenderID-PRA-Method Result: pass(domain.com: domain of
domain.com designates x.x.x.x as permitted sender)

DomainKey-Status: good

DKIM-Status: failed (no signature found)

DKIM fails because its not installed...

-----------------

Yahoo! still fails.

Hotmail is Okay! At least with my test email address it goes to Inbox.

Thanks

ALL FIXED..

LOL I emailed Yahoo! and everything.. Tonight I sent off a few emails using Thunderbird and they got through fine.. I was 'Wow, Yahoo! gets on top of everything right away'
Then I sent through Webmail using Horde and back to Bulk.. I noticed the only difference in the headers was the Originating Client and some DNS info.. And in the middle it said "My Name" email@domain.com....
Well i went and checked WebMail to see if I had set up my name... And nope, it was blank... Added my name and sent off another email to Yahoo! And it went to the Inbox...

I feel like i wasted a week on this... LOL..
Well that should teach me.. I guess Yahoo! filters SPAMMERS by that...
