I have been running a Dovecot based mail server for over 10 years and it is time (really past) to upgrade.
I really don't want to roll my own anymore. Too much time and too many skills needed. Time to retire. But still want it 'in-house'.
What I am seeing is that many of the packages seem to roll the messages into some SQL database. My Dovecot setup uses the /home/vmail/doman/../{cur,new,etc} tree structure.
Is there any pros vs cons on this that I can read?
Is there some nice packed mailserver I can drop on a Centos-arm server that has Dovecot under the covers and I can easily rsync my current mail store to it?
Mail-in-a-box looks interesting. But I have not figured out its internals and if I have to worry about anything compiled for arm that is not part of the distro.
Thanks in advance for help.
