Hello, we are running Dovecot (2.2.13-12~deb8u1) on Debian stable. Configured with Mailbox++, IMAP, POP3, LMTPD, Managesieved, ACL. Mailboxes are on local 1.2TB RAID, it's about 5310 accounts. We are slowly getting out of space and we are considering to move Mailboxes onto Netapp disk array with two independent network connections. Are there some pitfalls? Not sure we should use NTP or iSCSI mounts (both open implementations are not so shiny). Thanks for sharing any experiences. Kind regards, Milo
I chose nfs for my env because I wanted multiple load balanced instances of dovecot to be able to access the mailbox files. If you use iscsi, you will need to pin the user to the dovecot instance that has the LUN mounted. For me, scalability and single point of failure was lost or lessened when using iscsi.

Hi, thank you both for hints. I'm still not sure what to choose, so I'll probably test it on some dev installation.
