sendmail not invoking dovecot-lda
hi dovecot mailinglist
- Configuration FreeBSD-9.3 sendmail -d0.1 == sendmail-8.14.9 <<-- dovecot --version == dovecot-2.2.15
===================================================================
I'm trying to get sendmail to invoke dovecot.m4 ( dovecot-lda ) to
deliver emails to dovecot's virtual users ( /etc/dovecot/passwd )
or mysql/postgresql virtual users
sendmail -bv dovecot.VirtualUser@localhost --> returns "User Unknown"
cat test.msg.txt | dovecot-lda -d dovecot.VirtualUser ===> works
email is delivered to dovecot.VirtualUser inbox
===================================================================
- there are tons of howto and comments for dovecot + postfix and very little for dovecot + sendmail ... therefore, it'd be great if we/i can get this dovecot.m4 problem resolved
- status of what works and what does NOT work while testing dovecot's LDA ...
#
# fyi.. recepient user is in the form of user, user@localhost and user@domain.com
#
sendmail -bv user.in/etc/passwd = deliverable
sendmail -bv user.in/etc/mail/virtusertable = deliverable to sendmail virtual user-->> sendmail -bv dovecot.user.in/dovecot/virtual.passwd.file == user unknown
dovecot user user.in/etc/passwd == returns UID/GID/home/mailbox ( deliverable )
dovecot user dovecot.user == returns UID/GID/home/mailbox ( deliverable )
# --------------------------------------------------------------------
# dovecot's LDA delivers the test email to the dovecot/mysql recepient
# --------------------------------------------------------------------
cat test-email-with-headers.txt | dovecot-lda -d dovecot.user ( email delivered )
# ------------------------------------------------------------------>> # mail/mutt/sendmail canNOT deliver to dovecot recepient == FAILS # ---------------------------------------------------------------- -->> sendmail -bv dovecot.user.in/dovecot/virtual.passwd.file == user unknown 3 echo "testing mail to dovecot" | mail -v -s "testing mail to dovecot" doveccot.user == user unknown ==

Take note of the remark "reject unknown users early".
- your mailer is named "dovecot", therefore the mailertable entry in the Wiki:
virtualdomain.example.com vmail:vmail
should spell, IMHO:
virtualdomain.example.com dovecot:dovecot
(2nd dovecot has no meaning, but there must be present something)
- Post a sensable output:
echo '3,0 dovecotuser@dovecot.domain' | sendmail -bt -d21.4
- there had been a post about trying to improve virtual user support in sendmail incl. some ongoing talk. Maybe you find it and get some info back into this list.

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
http://www.sendmail.org/~ca/email/other/cagreg.html# ================
# testing dovecot to fetch the emails
# ================
dovecot.user is only defined in /etc/dovecot/passwd
echo "test mail" | mail -v dovecot.user@vmail.example.com
echo "test mutt" | mutt -s mutt dovecot.user@vmail.example.com
echo "sendmail" | sendmail -d60.5 -d27.2 -bv dovecot.user@vmail.example.com
telnet vmail.example.com 110
openssl s_client -connect vmail.example.com:995 # pop3s
user dovecot.user
pass passwd
list
retr 1
quit
telnet vmail.example.com 143
openssl s_client -connect vmail.example.com:993 # imaps
a1 login dovecot.user passwd
a2 LIST "" "*"
a3 select INBOX
a4 FETCH 1 BODY[]
a5 logout
# replace gmail.com with your ssl-enabled dovecot server
openssl s_client -connect pop.gmail.com:995 -showcerts
openssl s_client -connect imap.gmail.com:993 -showcerts
# replace gmail.com with your SASL enabled STMPT server
openssl s_client -connect smtp.gmail.com:587 -starttls smtp
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
virtualdomain.example.com dovecot:dovecot (2nd dovecot has no meaning, but there must be present something)
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
dovecot.yser@fake... deliverable: mailer esmtp, host fake, user dovecot.plain@fake
sendmail -d60.5 -d27.2 -bv dovecot.user
# -d60.5 should trace map lookups (including mailertable)
# -d27.2 should trace alias expansion
echo '3,0 dovecot.user@localhost ' | sendmail -bt -d21.12 -d60.5
# -d60.5 tracking maps (virtusertable) lookups
# -d21.12 tracking processing of R lines in sendmail.cf
sendmail -d27.2 -bv dovecot.user
# -d27.2 tracking processing of aliases
sendmail -Am -bv dovecot.user@vmail < /dev/null
echo '3,0 dovecot.user@vmail.example.com' | sendmail -Am -bv dovecot.user@vmail.example.com
dovecot.user@vmail.example.com.. deliverable: mailer dovecot, host vmail, user dovecot.user@vmail.example.com
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 To: vmail.example.com RELAY
dovecot user dovecot.user == returns UID/GID/home/mailbox ( deliverable )
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
these are good tests to show dovecot is able to deliver its emails
"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 ..
REMOVE define/feature to do with procmail
use Mailer(dovecot) instead .... Feature and Mailer is mutually exclusive in this case
take out procmail stuff
note i'm using "S=EnvFromL/HdrFromL" NOT "S=EnvFromSMTP/HdrFromSMTP" and similarly for R=
End of sendmail.cf
should wiki2.dovecot.org be updated to show
S=EnvFromL/HdrFromL, R=EnvToL/HdrToL,T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u
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
http://dovecot.org/pipermail/dovecot/2013-January/087658.html
didn't work for me
