unrouteable address

hello

i get to receive mails on my server, but not to send

checklist:
1) my server has a hostname
2) the hostname resolves to my server main IP
3) the server main IP has a reverse DNS to my hostname
4) the remote domain and E-Mail is OK (i use this E-Mail for years and it's my ISP E-Mail)
5) when I check my domain on dnsreport.com, i don't get any errors
6) i have a root aliases on /etc/aliases and it points to a local domain E-Mail address
7) /etc/hosts has the main IP assigned to the hostname
8) -su-2.05b# host terra.com.br
terra.com.br has address 200.176.3.142
terra.com.br mail is handled (pri=10) by mx.terra.com.br


-su-2.05b# mail -v someemail@terra.com.br
Subject: test
won't work
EOT

I also see this error on my exim_mainlog (that's for another test)

2004-12-11 17:34:42 1CdD0h-0000dw-By == someemail@terra.com.br R=lookuphost T=remote_smtp defer (0): SMTP error from remote mailer after RCPT TO:<someemail@terra.com.br>: host mx.terra.com.br [200.154.55.2]: 450 Client host rejected: cannot find your hostname, [66.246.XXX.XXX]
(remember I said it's resolving... see below)

*** Looking up 66.246.XXX.XXX
(DNS) Resolved 66.246.XXX.XXX to server02.domain.com (66.246.XXX.XXX)
does anyone have suggestions?

thanks in advance


PS: sorry the obfuscating... I didn't reveal the E-Mail address because it may be used by spammers... and i think the "username" doesn't matter
and i didn't reveal the IP and hostname of the server because i'm still configuring it (it may have some security branchs)
