(email) server connection problem : Help
I am Running a mail server (postfix / dovecot) on FreeBSD 8.1
I have 6 different domain names configured with 6 different ip addresses.
I cannot log into the server via either ssl for email or ssh on the two
domains that are .org and .info
The connection is refused. Here is an example copied from a console;
shell$ ssh -l LoginName mail.anadarkohs60.com
The authenticity of host 'mail.domain_4.com(xx.yy.zzb.174)' can't be
established.
DSA key fingerprint is {snip}
Are you sure you want to continue connecting (yes/no)? no
Host key verification failed.
shell$ ssh -l LoginName mail.domain_3.org
ssh: connect to host mail.domain_3.org port 22: Connection refused
shell$
My guess is that it might be sshguard but I see nothing in the logfiles.
I can ping to the TLD, mx records, etc check out. Everything works
except for my .org and .info domain
Any help is greatly appreciated. I hope it is one of those simple
things I missed.
Thanks in advance

Are you sure you want to continue connecting (yes/no)? no
Host key verification failed.
By telling it no here, you've instructed SSH to treat the host key as invalid;
the connection will be closed.
shell$ ssh -l LoginName mail.domain_3.org
ssh: connect to host mail.domain_3.org port 22: Connection refused
shell$
There's no such domain as mail.domain_3.org in the public DNS.
Presumably you've changed this information; all I can conclude is that
whichever IP address the actual name resolves to isn't running SSH (or it's not
listening on that particular IP, or a firewall is blocking it, etc).

I changed it but here are the actual hostnames:

DNS checks out.
I think I am running ssl. I am checking postfix and dovecot. The odd
thing is the ssh. I looked at some old troubleshooting tips and ran
netstat -anf inet and this is what it returned

Re: (email) server connection problem : Help -- SOLVED
I want to thank everyone who helped me with this. It turned out that due to an administrative error, our hosting company had the ip addresses I was having trouble with routed to the wrong server. Everything is working now.
