dovecot - Aug 2022 - Adding new server (POP3 only)

Good morning,

we're facing a spike in users activation and we've decided to add 
another server for POP3 only.
Since our dovecot is currently backed by NFS, i'm under the impression 
we just need to add a new instance listening for POP3, backed by the 
same NFS. However, i'm afraid the existing POP3 users will download the 
messages once again, due to the fact the responding server will be on a 
different IP address, even if the hostname will be exactly the same.

Am i right in this assumption? Have you any advice for me?

Thanks
Antonino

Hi,

your users will not notice anything.

If you are using a load-balancer try to stick a user on the same 
back-end. Use "static" hash or Dovecot Director.
