SMTP banner and Junk mail

Hi!
I installed SMTP, POP3 server on Server 2003. I can send and receive emails, but my outgoing emails go to Junk mail.
If I do "telnet mail.xxxxxx.com 25" from outside, my SMTP responds with "220 ****2*************..." and long bunch of "*" and "2"...

I don't know about windows SMTP but 220 means service ready. Is your domain.com a registered domain or is it just a local? If it's not a registered domain and other servers do a DNS lookup, that could send it to the junk folder.

Yes! My domain is registered and can be pinged from outside by name, reversed address resolution works too, and I can receive emails without a trouble and they go to "Inbox" well...
But Outgoing mail goes to junk!
I am wondering whether it is about firewall: I keep TCP 25, 110 opened. Should I keep 53 opened for TCP and UDP for DNS resolution?

Of course, you don't want to block DNS. When you say it goes to junk, is it going to junk on your machine or is it going to junk on the intended receipients machine? If it's on your machine, there there is a filter or group policy that's doing that.

I fixed the SMTP greeting so it is in conventional form now: "220 mail.domain.com ESMTP...".
But mail goes to junk mail folder on a reciepient side.
