Check dovecot's logs If it does not help the push delivery of messages ni sendmail's queue in verbose mode: "sendmail -Am -v -q"
Well, the logs showed this:
Sep 21 21:47:08 openindiana sendmail[1208]: [ID 702911 mail.warning] gethostbyaddr(10.211.55.6) failed: 2 Sep 21 21:47:08 openindiana sendmail[1208]: [ID 702911 mail.warning] gethostbyaddr(IPv6:fec0::fea9:21c:42ff:feed:5f38) failed: 2
I have asked for _dovecot's_ logs. Your problem may be caused e.g. by sendail executing dovecot-lda "as wrong user".
So I put this in my /etc/hosts file:
10.211.55.6 localhost
And I added DOVECOT to my /etc/hosts 127.0.0.1 line.
*DO NOT* add DOVECOT (magic word in sendail config) to /etc/hosts.
This cleared the queue, but now all of the mail for the virtual users bounces with this: The original message was received at Wed, 2 Jan 2013 11:16:27 -0700 (MST) from openindiana [IPv6:::1]
----- The following addresses had permanent fatal errors ----- <hacwebstore@localhost> (reason: 550 5.1.1 User unknown) hacwebstore@DOVECOT (reason: 550 5.1.1 User unknown) (expanded from: <hacwebstore@localhost>)
----- Transcript of session follows ----- 550 5.1.1 hacwebstore@DOVECOT... User unknown 550 5.1.1 <hacwebstore@localhost>... User unknown
Then I took the DOVECOT out of the 127.0.0.1 line, and it still bounces with the same error.
How would I invoke this: "sendmail -Am -v -q" ? Change my startup script?
It is intended as one time debug help. It should show in more verbose way delivery attempts of messages staying in sendail's queue.
Another test: As root try to deliver message to virtual dovecot mailbox: /usr/lib/dovecot-lda -d hacwebstore
Please forgive me, Andrzej. I did not realize you wanted me to actually send you the logs. I thought you only meant for me to look to see if there was anything helpful in them.
They do not show much. If I restart dovecot and sendmail, this is basically what I get. If I try to send any mail, nothing shows up in dovecot's log. All that shows up anywhere is my logging into squirrelmail.

I had to modify the path to get it to work in Solaris. When I ran it as above, it sent a blank email to hacwebstore.
So, lda appears to be working, but sendmail doesn't?
Here is the dovecot portion of my sendmail.cf file again, for your convenience. Does it appear ok to you?

Thank you again, Andrzej, for all of your help with this. I appreciate it very much.
Do you think it is solvable?

Quick fix: Add S flag to F= section (F=DFMSPhnu9) of dovecot mailer spec abvove. Without U= section it should make sendmail execute dovecot-lda as root. U= section may request execution as specific user and group.
