Still trying to fit SmarterMail into an actual enterprise environment and digging into some more high availability options. Having multiple instances load balanced for SMTP/IMAP and webmail is what we'd like to do, but the file store is obviously the hold up. Has anybody put their SM datastore on an NFS share between two servers? Both servers could access the data, I'm curious what happens with file locking, permissions issues, etc. Or if you can run to edge smtp instances, both accepting inbound mail, writing to the spool, and then to the file store on the share.
Amazon is getting ready to release their "Elastic File System
" which is basically glorified NFS between instances. We run HyperV internally and are getting ready to test putting the datastore on an NFS share between two load balances VM's, but I wanted to know if anyone else has tested a setup like this.
