Error in Log file DSN: Service unavailable


Hello,

I am running a mail server.

Mails sent from our server do not get delievered to our client.

These mails succesfully get delievered to any other domain like gmail.com etc.

When I checked the log I found following error :

Apr 17 11:54:07 mx8 sendmail[13932]: r3H6O525013932: from=<sender@domain.com>, size=22065, class=0, nrcpts=1, msgid=<001301ce3b33$90fffef0$b2fffcd0$@com>, proto=ESMTP, daemon=MTA, relay=xx.xx.xx.xx.static-pune.hostin.in [xx.xx.xx.xx] (may be forged)

Apr 17 12:09:33 mx8 sendmail[19712]: r3H6O525013932: r3H6dJvf019712: DSN: Service unavailable

Please help me to solve this.

Thanks

There are 3 related errors here
Code:
Apr 17 11:55:29 mx8 sendmail[14069]: r3H6O525013932: to=<recipient@domain.com>, delay=00:01:22, xdelay=00:01:00, mailer=esmtp, pri=142065, relay=mx2.recipient.com. [xx.xx.xx.xx], dsn=4.0.0, stat=Deferred: Connection timed out with mx2.recipient.com.
Apr 17 12:09:33 mx8 sendmail[19712]: r3H6O525013932: to=<recipient@domain.com>, delay=00:15:26, xdelay=00:00:14, mailer=esmtp, pri=232065, relay=mx2.recipient.com. [xx.xx.xx.xx], dsn=5.0.0, stat=Service unavailable
Apr 17 12:09:33 mx8 sendmail[19712]: r3H6O525013932: r3H6dJvf019712: DSN: Service unavailable
The first is the key
' Connection timed out with mx2.recipient.com.'.
You need to check this, maybe by talking to the Admin of that box and/or try telnet by hand to port 25 on that box; can you reach it it and does it have a listening MTA on port 25.

Incidentally, this ' relay=xx.xx.xx.xx.static-pune.hostin.in [xx.xx.xx.xx] (may be forged)' is not really good either, but may not be fatal.

This "relay=xx.xx.xx.xx.static-pune.hostin.in [xx.xx.xx.xx]" is our
shared hosting email server there are lot of client on it not having any problem
while sending/receiving emails.

Any Idea?

You need to talk to the admin of that server mx2.recipient.com. He can watch the logs while you try to do that.
He should know anyway; looks like your local system is not an acceptable system for them.

Re other problem; you should try to get to the bottom of that also. It may(?) not seem to be causing a problem right now, but in the long run it may come back to bite you.
