Hello,
i'm thinking using 3 james frontends (with a alteon in front to do round
robin) that is configured with the same mysql database (with users,
spool, inbox and error tables). Any comments on this architecture
(databases lock, etc) ?
Standard James distribution will not work in that environment: James
needs locks working on the repositories.
There is a JamesHA (high availability) project on sourceforge. IIRC It
basically implements the repository locking using javaspaces.
You can alternatively start by splitting the services to different
computer:
1) one or more SMTP relaying servers to handle your incoming/outgoig
mail (they does not have local users, only incoming/outgoing spools)
2) one or more POP3 servers that only handle incoming mails from the
above SMTP servers and only handle mails for specific subgroups of users
(using a rule that you can apply to your alteon)
