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 -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -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 .libs/istream-openssl.o iostream-openssl-context.c:9:28: openssl/engine.h: No such file or directory iostream-openssl-context.c: In function ssl_iostream_deinit_global': iostream-openssl-context.c:431: warning: implicit declaration of function ENGINE_finish' iostream-openssl-context.c:432: warning: implicit declaration of function `ENGINE_cleanup' ...

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?
