This has never been my email address. I don't know who it goes to.
After reading the archives recently on a few threads about NFS I have concerns
You've read http://dovecot.org/list/dovecot/2010-August/052188.html thread?
over our plans to move from cyrus to dovecot, we initially discounted dovecot as a choice over it, but since dovecot and sieve go well together, I am just re-capping everything before we approve move to courier or back to dovecot, having re read those threads over a couple of times, am I right in assuming that this caching problem, is really only a problem if using imap and the chances of it being an issue with pop3 is very rare?
With POP3-only users it should be rare. But if they're using webmail also that adds IMAP there which makes it less safe. Also with POP3 you might want to disable indexes anyway and use filename as POP3 UIDL and then corruption wouldn't matter at all (dovecot-uidlist file updates are actually pretty pointless then).
Also, will this be more of a problem if we use dovecot v1.2 or v2.0 ?
They work identically. Although today I made performance improvements to POP3, and I'll probably still make some more.
Anyway, I can't give you any guarantees. I only know that it's not 100% safe, but some people with POP3-only/mostly setups have been happy enough anyway.
