SMTP and SPAM

[ScathDeSolas]

So two issues. I have sending of mail working in Thunderbird, only issue is I had to modify mail to be DOMAIN.COM instead of MAIL.DOMAIN.COM and outbound mail works as SMTP.DOMAIN.COM and DOMAIN.COM, weird... but I had to make it STARTTLS instead of NONE for it to work... Plus it requires a certificate to send mail.. WTF! How do I get rid of this certificate bull and just use IMAP or POP?! It auto-configures to IMAP Incoming and SMTP for Outgoing, REALLY ANNOYING.

SPAM ISSUES:
All of my e-mails I send EVEN on the same domain goes straight to Thunderbirds and LOCAL SquirrelMail's Junk/Spam Folder... WHY!? This means clients will miss my e-mails.


OTHER ISSUE:
In the exim mainlog file this is in it after sending e-mails. My nameservers for my site is NS1.CRYOFUZE.COM/NS2 So... why is it set to the servers nameserver? (XX's are just to hide my IP)

I see a few things, first your SSL certificate is expired, you might want to update it. Doing a scan of your dns, I found these issues:

Your MX records that were reported by your nameservers are:

10   smtp.cryofuze.com   69.195.141.20
10   mail.cryofuze.com   No A Record (no glue either) 

ERROR: No reverse DNS (PTR) entries. The problem MX records are:
20.141.195.69.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips

You don't have an A record for mail.cryofuze.com which would explain why you couldn't use it to send mail, it must have got deleted, since I know DA always sets it by default.

To fix the straight to spam, get your reverse DNS configured correctly.

Also, the reason changing it to starttls worked, was that you changed the outgoing port. Most (if not all) ISP's today block sending email on port 25, to external mail servers. DA today also configures port 587 for sending emails, you might want to try that one.
