I have searched this forum extensively and can't seem to find a workable solution to my sendmail issue, but that could be down to my own lack of knowledge so please bear with me...

I am using a Sun Solaris 9 box to try and send e-mail to external addresses. The Unix box is not an e-mail server. Our e-mail is done through a third party ISP i.e. POP3 accounts, complete with user names and passwords.

I'm using sendmail version 8.12.2+Sun and I have made a number of changes (rightly or wrongly) to /etc/mail/sendmail.cf & /etc/init.d/sendmail based on details found on www.kempston.net.

The problem I'm having is this.

When I send a mail to my external address the mail is queued, I can see it in mailq, but it never gets sent.

I can telnet onto port 25 and can see sendmail is running.

I can also see send mail running when I us "ps".


root 5392 1 0 12:13:45 ? 0:00 /usr/lib/sendmail -bd -X /var/log/mail.log -oL9
smmsp 5393 1 0 12:13:45 ? 0:00 /usr/lib/sendmail -Ac -q15m

NOTE: I edited /etc/init.d/sendmail to add the "-X /var/log/mail.log" line ...

The changes to the /etc/mail/sendmail.cf are as follows:

! # "Smart" relay host (may be null)
! DSmailhost$?m.$m$.

Changed to read.....

! # "Smart" relay host (may be null)
! DSmail.mailhost.com

Where mail.mailhost.com is the SMTP server.

! # avoid connecting to "expensive" mailers on initial submission?
! O HoldExpensive=False

Changed to read ......

! # avoid connecting to "expensive" mailers on initial submission?
! O HoldExpensive=True

Added in an entry to read ......

- # Don't Use DNS
- O ResolverOptions=-DNSRCH

Also changed line .....

! Mrelay, P=[IPC], F=mDFMuXa8, S=EnvFromSMTP/HdrFromSMTP, R=MasqSMTP, E=\r\n, L=2040,

Added in "e" after "F=".....

! Mrelay, P=[IPC], F=emDFMuXa8, S=EnvFromSMTP/HdrFromSMTP, R=MasqSMTP, E=\r\n, L=2040,


And also added in rule S11 ....

- S11
- R$* $@ me@domain.com

Where me@domain.com is my actual e-mail address .....

I have also edited the /etc/hosts file to include:

xxx.xxx.x.x servername servername.domain loghost

Where the domain part is the text after the @ of my mail address, the IP is local.

And also added

xxx.xx.xx.x mail.mymailhost.com mailhost

Where the mymailhost is the SMTP server and the IP is the primary DNS IP

When I run the following command:

/usr/lib/sendmail –d0.1 –bt < /dev/null

I get the following output …

# /usr/lib/sendmail -d0.1 -bt < /dev/null

I have been testing this with the following simple script:

# more send_mail

SUBJ="Send mail from Unix with file attachments"
TO=me@domain.com
(
cat << !
To : ${TO}
Subject : ${SUBJ}
!

cat << !
HOPE THIS WORKS
you got the mail from sendmail utility
!

uuencode test.txt test.txt

) | /usr/lib/sendmail -v ${TO} ${CC}
#

Which produces the following output:

The mailq produces the following:

The log file /var/log/mail.log looks like this:

I can see the message in queued in /var/spool/mqueue

So why is it not reaching the destination e-mail account?

What am I missing?
