The dovecot version (2.2.10) we were running had a timing window problem in the context of replication (we use maildir on CentOS 7). After doing elaborate tests to isolate the problem, we wound up upgrading to 2.2.23. That fixed it, and that version has been very reliable. Recently we receiv

We have been running Dovecot 2.2.10 with a pair of CentOS 7 boxes with replications for the past year. We have been quite happy with the performance and reliability. Recently we received a report from an Android IMAP user that emails that he deleted without reading would often reappear in his

A few days back, I sent an overview of this problem, but received no responses. Since then, I have run dozens of traces to isolate the problem, difficult because there are timing issues involved. I have finally nailed it down. If this is not the proper place to report such bugs or if someon

We tested dovecot for a fair amount of time and decided finally to put it into production under CentOS 7 (we are running 2.2.10). I just joined the list, so I apologize for what is probably a question that has been answered many times, but I was wondering if there are any plans to implement re

Hitting wall at 2048 IMAP connections

We are gradually rolling out Dovecot (IMAP only, no POP3) to our customer base. We are replicating between a pair of CentOS 7 boxes. All has been working wonderfully. However, to be sure our rollout continues to go smoothly, we put together a simple benchmark client program to fire up X pers
