Hallo

I can not find a forum at dovecot.org and I get a problem I can not solve.

After Updating to the version dovecot2  2.1.16  I can no more get eMails with my eMail-client. All has been working fine before. Server: FreeBSD 10.0-RELEASE-p18, with perl 5, version 18, subversion 4 (v5.18.4) It seems it is an authentication problem with my server. The errors are: #cat dovecot.log Apr 17 22:19:37 imap-login: Error: Timeout waiting for handshake from auth server. my pid=41810, input bytes=0 Apr 17 22:19:58 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Apr 17 22:19:58 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Apr 17 22:19:58 master: Error: service(auth): command startup failed, throttling for 60 secs Apr 17 22:24:04 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Apr 17 22:24:04 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Apr 17 22:24:04 master: Error: service(auth): command startup failed, throttling for 60 secs

I have google and has nothing found about "..environment corrupt; missing value for DOVECOT_" and about "auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address"

I have make a reinstall - but doesn't help. I get the same error. I have not forget to create new certs with the dovecote shell-script after installation.

I'm using passwd (virtual users). Make a cat on passwd shows that it is not empty. Also the date of the file show that the update installation has it not changed. So I have not create the dovecot users again. here are some other logs: #cat dovecot-info.log Apr 17 22:29:03 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS handshaking Apr 17 22:29:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS Apr 17 22:29:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS
