Hello, I want to setup dovecot with two postfix servers on three machines: - dovecot - with huge amount of disk space - where all user emails will be kept, - postfix1 - with greylisting, amavisd-new (spamassassin, clamav, etc), with mysql backend, - postfix2 - same as postfix1. MX priority will be set to the same value for both postfix machines.
For now I don't know how to "glue" these severs: - if I should install dovecot on both postfix and use third servers as a NFS share? - or maybe it is possible to communicate with dovecot on third server via LMTP? - or should I run third postfix daemon (without antyspam etc - simple configuration) on the same machine as dovecot only for delivering local mails? I will be grateful for any advice, howto or good practices example. -- Regards, Thomas.
