hi steffen
- thanx for your reply
sendmail-8.15.1 + dovecot-2.2.15 + OpenSSL is working ..
my sendmail is also configured for smtp-auth and saslauth
and seems to work with dovecot
one other thing to note, sendmail requires CA signed *.pem certs
vs self-signed ... in my case, dovecot uses the same *.pem certs

it turns out, the hostname must NOT be listed in /etc/mail/local-host-names
and that it still must resolve ( /etc/hosts )

and again, virtualdomain -- should NOT be listed in /etc/mail/local-host-names
- when i removed it from local-host-names, things started be more debuggable
and fixed
yup

it's working ... other sendmail tests ...
# sendmail -d60.5 -d27.2 -bv dovecot.user
# dovecot.user... User unknown
#
# sendmail -d60.5 -d27.2 -bv dovecot.user@fake

few posts showed another sendmail file that needs to be configured
/etc/mail/access
# vmail must be defined in /etc/hosts ... NOT listed in local-host-named

these are good tests to show dovecot is able to deliver its emails
in my case, dovecot resolves users in /etc/passwd, /etc/mail/virtusertable,
/etc/dovecot/password
and hopefully, it will also resolve /usr/local/mysql database users

"user unknown" comes from misconfigured since sendmail is still confused
- /etc/mail/mailertable
- /etc/mail/local-host-names
- /etc/mail/access
my final sendmail config .... only import stuff shown ..

use Mailer(dovecot) instead .... Feature and Mailer is mutually exclusive in
this case

should wiki2.dovecot.org be updated to show

for debugging purproses .... it is very helpful to use a wrapper script (
wraplda.sh )
around dovecot-lda to get UID/GID info of who is calling dovecot-lda
