we are experiencing similar sporadic data timeout issues with dovecot 2.0.20 as in http://dovecot.org/pipermail/dovecot/2011-June/059807.html at least once a week. Some mails get temporarily deferred in the postfix queue since dovecot director lmtp refuses them and the mails are delivered at a later time.
What isn't in v2.0 is the larger rewrite of the LMTP proxying code in v2.1, which I hope fixes also this timeout problem.
Same problem persists after update to 2.1.7, especially for distribution lists which contain several target email addresses which are then pipelined by postfix through a single lmtp proxy connection:

Hello,
I had a similar issue. This data timeout is reported for all recipients in the same lmtp connection? What is the start time of the lmtp connection?
My problem was that this timeout seems to be counted from the beginning of the LMTP connection, so when I have a lot of recipients in the same connection, last ones sometimes timedout. I solved it increasing this timeout with proxy_timeout option and reducing max number of lmtp recipients in postfix.
