Perhaps there's a setuid root binary at /usr/bin/sendmail
or /usr/lib/sendmail that belongs to exim?

Dear Aaron,

I have tried several options. 

On your lead, tried using Exim's trusted_users and trusted_groups to
include dbmail/dbmail as user and group combination. Then DBMail
started reporting an error in dbmail.err log indicating the following,
giving the old result of not delivering the messages.


2007-05-29 10:10:40 Failed to create spool
file /var/spool/Exim/outgoing/input/1HstVg-0001wn-5P-D: Permission
denied


This does not look like an error generated by DBMail, possibly
generated by Exim but logged by DBMail.


Then I've changed to "EFFECTIVE_GROUP = exim" while having
"EFFECTIVE_USER = dbmail", still reported the same error. Then I've
changed the group privileges of the spool directories as chmod g
+rws /var/spool/Exim/outgoing/{input,msglog}, which made the
deliveries to dbmail-lmtpd successful.  

I am yet not fully satisfied, there are other Exim compilation options
(EXIMDB_DIRECTORY_MODE, EXIMDB_MODE, INPUT_DIRECTORY_MODE,
SPOOL_DIRECTORY_MODE, SPOOL_MODE) which I should try. Though I do not
plan immediately, when I try these options, will keep you updated.
However, for the time being, I will be using exim/exim user and group
combination.

Thanks for all the help offered.

Kind regards,

Lasantha.

Dear Aaron,

Yes I do agree with you on separate users for Exim and DBMail. I
will work on it and come back to you.

Lasantha.

I thought about this some more, and I don't think this is correct.
Doesn't exim have a sendmail emulator? This chapter looks relevant:


http://exim.org/exim-html-current/doc/html/spec_html/ch05.html

If you don't mind playing with your configuration a little bit more, I
think it will be preferable to have DBMail and Exim running as separate
users.
