Postfix Connection timed out port 25

It isn't a TLS / postfix issue, look the log:

[root@142358 sysconfig]# postqueue -p
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
89CDE108C8710     6488 Thu Jul 14 15:33:52  dulcevilela@carvalhovilela.com.br
            (connect to mx.uol.com.br[200.147.36.15]:25: Connection timed out)
                                         ricardohilkner@uol.com.br

The other server does not accept email (IN) on port 25.

The port is closed/blocked. When I try a telnet I have the same answer:

[root@142358 sysconfig]# telnet mx.uol.com.br 25
Trying 200.147.36.15...
telnet: connect to address 200.147.36.15: Connection timed out
[root@142358 sysconfig]#

Any idea?

Thanks!

Just a comment before to close.

Some Brazilian Mail Server does not allow connection at port 25 from IP's of my host / ISP.
As my host/ISP can't change it, I have 2 choices:
1- Contact each company/mailserver that is blocking my connections and ask to allow;
2- Change my current Host/ISP.

I choose to change my Host, and I am migrating to Interserver

It's done!
