[Dovecot] Multiple instances of dovecot in the same machine.

Hello all,

I'm trying to run several instances of dovecot, with a different config each one, following the instructions from here:

http://wiki.dovecot.org/RunningDovecot

I try the command

dovecot -c /etc/dovecot/installN/dovecot.conf

and get:

Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Fatal: Invalid configuration in /etc/dovecot/installN

but in my /etc/dovecot/installN/dovecot.conf file I have these lines:

ssl_cert_file = /etc/dovecot/installN/ssl/certs/dovecot.pem ssl_key_file = /etc/dovecot/installN/ssl/private/dovecot.pem

where both files exist and are valid. Any help is appreciated.

Thanks, Rodolfo.
