Message getting dealyed by 7 days before retry

[konidala]

Hello all,

set up
-------
we use sendmail as our e-mail server on the public side which delivers e-mails to our internal exchange server.here 10.6.4.128 is our internal exchange server.

Problem
--------

we recieved an e-mail on 19th oct which is processed by sendmail and tried to send it to our exchange server but it was unavilable at that moment so the connection was refused.

maillog.7:Oct 19 18:53:12 monster monster-mta[20592]: i9K1r6Wc029291: to=<megastar@chiru.com>, delay=00:00:06, xdelay=00:00:00, mailer=esmtp, pri=129758, relay=[10.6.4.128] [10.6.4.128], dsn=4.0.0, stat=Deferred: Connection refused by [10.6.4.128]


and after 7 days only sendmail tried to deliver this mail.
I am a beginner usind sendmail. I dont know what setting to tweak to make send mail try after 1 day of connection refused.
