Since you have full root access, you control the volume mapping. We recommend
mounting your Docker volumes (/var/lib/docker/volumes) onto a
separate RAID-1 NVMe partition. This ensures that even if you
destroy or update the containers, your mail data (vmail), database, and DKIM
keys remain persistent and safe.
ClamAV loads its entire virus signature database into RAM for speed, which often consumes 1GB to 1.5GB of memory alone. If you are running a server with less than 8GB RAM, we recommend disabling ClamAV (using Rspamd for spam filtering instead) or upgrading your RAM. On a ServerMO dedicated server, you have the hardware resources to run it comfortably.
Yes.imapsync is the industry-standard tool for
this. Since you have CLI access, you can install imapsync and run a script to
pull emails via IMAP from Google/Microsoft and push them to your new
Dovecot/Postfix server. We don't block any outgoing IMAP connections, so the
migration speed depends entirely on the source provider's throttle limits.
Yes. MTA-STS (Strict Transport Security) and DANE (DNS-based Authentication of Named Entities) are DNS and SSL configurations that you manage. Our network fully supports TLSA records and HTTPS policy hosting required for these advanced security protocols to prevent downgrade attacks.
It is optional but recommended for future-proofing. However, deliverability warning: Gmail and Outlook are extremely strict with IPv6. If you enable IPv6 in Postfix, you MUST ensure your AAAA record and PTR record (Reverse DNS) for the IPv6 address match perfectly, or your emails will bounce. We provide full IPv6 rDNS control in our panel.
