Hi,

See the mail is trying to get delivered to the MX mx.uol.com.br[
200.221.29.129]:25

Have you checked if this server response to any server sending mail to it is
fast enough?

please check it.. this MX's MTA might not be responding in given time when
you attempt to send a mail. This should be an issue of mx.uol.com.br[
200.221.29.129]:25 not at your end...

 try sending a test mail to other domain and check it.
