Just posting this for a heads up. Not a question, just info. We just switched from "Cyrus deliver" to "LMTP" transport.
from: mail_transport=cyrus to: mail_transport=lmtp Once we reached about 600 user we were having problems with: - corrupt mailboxes (needed to be reconstructed) - cyrus deliver program freezing (no new messages) We switched to use LMTP for the Postfix transport. All of our problems went away and the system performance has improved noticeably. Unfortunately, I never located the specific issues that were causing our problems. This did fix it though. I thought this might be helpful for others searching the archives.
