Good day Guys
Just wanted to pick the communities brain and experience(s) for a second.
At $CORP where I work. My team has inherited a single server mail solution.
We need to look to building a standby / replicated solution.
One of the things we were looking at is https://wiki.dovecot.org/Replication
We have in excess of +/- 500 mail boxes and using just under 1TB of disk space. That is a lot of small files.
Reading about this plugin / module, things that stick out and is concerning is the comments:
"The replication in general is a bit resource intensive, so it's not recommended to be used in multi-million user installations."
"WARNING: Shared folder replication doesn't work correctly right now –"
I would like to ask the community (and anyone else in a similar enterprise) how and if this solution works and scales.
In short, I am asking, is anyone else using Dovecot Replication in a medium to large enterprise? Can you please share your experiences, pitfalls and if you have any tips managing mail replication.
Kindest regards and thanks in advance. Brent Clark
