Hello,
Do you think Dovecot could handle millions of active users in a big architecture ?
This cluster could be for example (each server is a bi quad Xeon 2.66 Ghz) :
- 40 Dovecot servers
- 4 LVS
- 20 Apache+PHP
- 2 Openldap
- 20 Postfix + ClamAV + SpamAssassin
- 1 NFS Netapps
For millions of user it could be multiple different clusters of 40 Dovecot servers with 1 Netapp for each cluster. I want to work in NFS. I've experimented problem with Cyrus and NFS on Netapp. I want to use maildir, I can manage limitations of inodes with Netapp.
I know webmail.us use Dovecot, what is the most big dovecot architecture known ? Do you think Dovecot can handle 1 million of active users in a good architecture ? Do you think it's a good solution to use one synchronised local Openldap on each server Dovecot ? Do you think It's possible to use Postgresql or MySQL instead of Openldap ? Are cyrus or courrier-imap better solutions ? Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy in this architecture, is Dovecot scalable ?
Thank you for your ideas.
Regards.
John Fistack
