I ran into two issues trying to upgrade our dovecot installation (Solaris 10).
1) Does not compile with OpenSSL 0.9.7
Not a big deal, as I was able to successfully against OpenSSL 0.9.8,
but does dovecot require OpenSSL >= 0.9.8 now?
libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib
-I../../src/lib-test -std=gnu99 -O3 -fomit-frame-pointer -mcpu=ultrasparc -Wall

-Wformat=2 -Wbad-function-cast -fno-builtin-strftime -MT istream-openssl.lo -MD
-MP -MF .deps/istream-openssl.Tpo -c istream-openssl.c -fPIC -DPIC -o

2) Dovecot's LDA does not work
After stopping the the old dovecot, and starting dovecot 2.1.3 using tghe
exact same config file, local mail delivery tempfails:
Mar 23 02:51:51 server dovecot: auth: Error: getpeerucred() failed: Bad
address
Mar 23 02:51:51 server dovecot: auth: Error: userdb connection: Failed to get
peer's credentials
Mar 23 02:51:51 server dovecot: lda: Error: userdb lookup(j.tam): Disconnected
unexpectedly
Mar 23 02:51:51 server dovecot: lda: Fatal: Internal error occurred. Refer to
server log for more information.
# Sendmail reports
stat=Deferred: local mailer (/var/dovecot/libexec/dovecot-lda) exited with
EX_TEMPFAIL
After seeing 2) in the logs, I had to revert back to 2.0.16. Any hints
on what could be wrong?
