Dovecot has no problem with virtual users, but Sendmail's idea of virtual users is not quite as 'virtual'.
One possible solution: http://www.cs.fsu.edu/~langley/USVH-tr.pdf That was 2007.. so perhaps somebody has written this up in a more concise way..
or you can wrestle with ldap. :-(
or switch MTAs.

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems.
I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with, though. If not, please let me know.
I initially used this Dovecot wiki page to approach this: Simple Virtual User Installation
http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall
I had to make few minor changes, but I don't think anything significant to the problem I'm having.
I can log into SquirrelMail with both virtual users, and with system users.
I can send mail to system users from both virtual and system users.
I can see the mail that I sent in the Sent Messages folder for both types of users.
I just can't send mail to virtual users. When I try to, I get the following message:
ERROR: Message not sent. Server replied: Requested action not taken: mailbox unavailable 550 5.1.1 <dswebstore@localhost>... User unknown My configuration info is as follows:

My dovecot password file looks something like this, though changed for obvious security reasons:
systemuser:{PLAIN} systemuserPASS virtualuser1:{PLAIN}virtualuser1PASS virtualuser2:{PLAIN}virtualuser2PASS
I read on this page that I needed to put the following in my sendmail dovecot.m4 file:
Dovecot LDA with Sendmail http://wiki2.dovecot.org/LDA/Sendmail
So this is my dovecot.m4 file, which shows up in my sendmail.cf file after recompiling my sendmail.mc file.
######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u
Finally, this is my sendmail.mc file:

I think it is obvious that it is a problem with Sendmail not recognizing Dovecot's virtual users. But how do I fix it?
If anyone could help me with this, I would *greatly* appreciate it. I've been picking away at this for about three weeks now, and I'm pretty much out of ideas of anything else to try.
Cordially,
