Resent to list, since my previous direct emails to Timo have gone unanswered I am NOT a member of this list so Timo please reply direct
I do not wish responses from those who are not developers of dovecot, many I have since had discussions with on another list and spam binned (abusive souls like charlie marcus) some for trolling, I seek a definitive answer and there is only one man who can give this, but I likely was mailing a old address he doesn't read

After reading the archives recently on a few threads about NFS I have concerns 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? If this is the case, then we certainly would approve move to dovecot.
I note some people who have apparently much larger systems than us, say that they have seen no problems but others say they may have had just not noticed.
So, if smtp3 delivers to storage MailDir and pop3-1 connects to get mail - at the same time: no problem just wont see that message until next refresh at the same time: will see message
if smtp3 and smtp1 deliver at same time there lies the corruption issue? If so, it will be reindexed at next delivery or pop3?
Just trying to understand where it will be a problem, we will use postfix setting of virtual_transport = dovecot and dovecot_destination_recipient_limit = 1
We dont allow multiple logins either, we have only intention for one imap server, to compliment our two pop3's and 4 smtp's.
We intend to use -
pop3_lock_session=yes maildir_very_dirty_syncs=yes auth_verbose = yes auth_cache_size = 512 auth_cache_ttl = 3600 auth_cache_negative_ttl = 0 mail_location = maildir:/var/vmail/%1d/%d/%n/Maildir mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes
protocol lda { mail_plugins = quota cmusieve quota_full_tempfail = yes auth_socket_path = /var/run/dovecot/auth-master }
Also, will this be more of a problem if we use dovecot v1.2 or v2.0 ? (only examples of configs we have for our move is for v1.2 at present for debian)
Hope you do not mind me asking this in private, but given how those threads ended up in personal attacks, I would rather not reignite any fires.
