Hi! I am looking for a scalable, stable and cost effective webmail server solutions. The server system
- should be cost effective and based on open source softwares as possible ( could be commercial ) - should be scalable up to 200,000 users, but 150,000 a must - account creation or deletion should not exceed 2 seconds - could be support concurent 100 subscribers for webmail browsing on the system without any performance problems - should not be create real system user for mail or other purposes. Account information stored LDAP or other databases. - does not needed pop3 support - could ( i think should ) be cluster or similiar system ( load balance, round robin dns..., MUPDATE ) - Webmail system should be support basic webmail functionality like read, compose, mail, delete, folders, address book, able to view attachments... - users quota limit could be 1 MB or even 256 MB since webmail system is used only for special mail traffic ( MMS content ). - user accounts on the current Suse eMail server could be migratable to the new server. ( I think i needed write scripts ) - could be a bit high price hardware solutions ( my customer will provide hardwares ) I have looked Suse OpenExchange server, there are too many features that we dont need such as exchange server integration, projects, appointment etc. Its not cost effective solution any more due to client prices. I have looked Cyrus Murder configuration but i dont understand differences at the follow. I think that the system have 203069 users but only 26516 users have been using their mail box, am i right? mailboxes (*): 203069 user mailboxes (user.*): 173414 user INBOXes (user.%): 26516 I urgently need your software/hardware suggestion and/or experience to build new scalable, stable webmail system. - Any ready distribution ? ( like Suse eMail server ) - Which IMAP server ? ( Cyrus, Courirer or .. ) - LDAP based or ? - Postfix or Qmail? - How to scalable, distribute, load balance etc. servers? - About Cyrus MUPDATE: currently uses, tutorials, docs. - Some example hardware configurations ? - Any others... By the way, I have many experiences with Linux systems and also Java programming. So do not hesitate to advice some hacking ( not many or big, because time is very limited ) if it is really needed. Thanks in your advance. Erol __________________________________________________ Do you Yahoo!? Yahoo! Shopping - Send Flowers for Valentine's Day http://shopping.yahoo.com
