The new trend in firewall security is to block traffic both inbound and
outbound. Request that the firewall owner open port 25 from your solaris
box to the SMTP relay. They may ask what applicaiton you are running, it
would be 'SMTP'
Try testing on the solaris box by attempting to telnet to the SMTP server
on port 25, give it a HELO.
The other thing might be that they've updated their mail server to require
encryption prior to sending. I don't think your version of sendmail has
the capability to do SSL/TLS SMTP.

Hello Duc,
A number of years ago (doesn't time fly) I had a similar problem and came
up with this solution. Might not help, but worth a try.
Here's a section of the sendmail.cf file that I altered...
# my official hostname
#Dj$w.$m
# Hashed out line above and replaced with line below
# Mysteriously stopped working when the Exchange Server was changed
# the dot was being appended to the name e.g. 01AW01. and was
# confusing the server. Though it used to work before.
# $m=domain name and $w=hostname, just need to use hostname.

Subject: [foxboro] Send mail from Solaris through firewall
ââ¬â¹List,
I've spent a good part of three days banging my head against the
(fire)wall on this issue. Please help me before the blood soaks everything.
The situation: AW-D running Solaris 2.5.1 and sendmail 8.6, you know the
ancient version on the stock Sun boxes. I configured /etc/mail/sendmail.cf
years ago to send mail from this Sun box to the corporate e-mail and it's
been working all these years. Recently, we moved all these Sun boxes to
behind a fortified firewall, so fortified that even with a known relay mail
server, I have not been able to send mail to my desktop.
Previously, these are the only edits in my sendmail.cf (with
sendmail.cf.orig being the plain vanilla, stock sendmail.cf that came
with the software install), and it worked splendidly to send system status
reports to my corporate e-mail account:
04AW01# cd /etc/mail
04AW01# diff sendmail.cf.orig sendmail.cf
21c21
< Dj$w.$m
---
Dj04AW01.dowcorning.net27,28c27,28
< DRmailhost
< CRmailhost
---
DR
CR
I searched the freelists.org archive and found an excellent write up by
Sven Audenaert (thanks, Sven!) from Sept 2006 (
//www.freelists.org/post/foxboro/foxboro-Sendmail-error,2).
Following Sven's procedure, I added the mail relay in the hosts file, also
calling it "mailhost", and edited sendmail.cf accordingly. But that's
where my progress stopped.
Here's what I try to accomplish:
04AW01 ---> mailhost ---> smtp.dowcorning.net
originating relay server SMTP server destination
My new sendmail.cf (with sendmail.cf.orig being the plain vanilla, stock
sendmail.cf that came with the software install):
04AW01# diff sendmail.cf.orig sendmail.cf
21c21
< Dj$w.$m
---
Dj04AW01.dowcorning.net24c24
< DMether
---
DMmailhost
The most relevant part of sendmail.cf:
# my official hostname
Dj04AW01.dowcorning.net
# major relay mailer
DMmailhost
# major relay host
DRmailhost
CRmailhost
Yes, I stopped and started the sendmail daemon as needed after editing
sendmail.cf
When I try to run the test as in Sven's procedure, sendmail just hangs and
times out after 3 minutes or so.
Question: How do I specify the relay host in sendmail.cf to allow me to
send mail through it to the corporate mail server?
Thanks in advance for all the help. And I really need all the help at this
point.
Duc
