Keep your domains, mailboxes and historical email

We can perform the migration from CommuniGate Pro for you, with minimal downtime. Your old server stays untouched and reachable until you switch DNS.

• 10M+ Docker pulls
• 2014 shipping since
• 0 mailboxes lost

How it goes

CommuniGate Pro stores mail in its own format, so we migrate over IMAP - which is also the safest way to keep the old server running until you are happy.

• Domains, mailboxes and forwarders are recreated in poste.io.
• Historical email is synchronised over IMAP, folders and read state included.
• Per-domain settings and routing are mapped onto their poste.io equivalents.
• The old server stays untouched and reachable until you switch DNS.

What you get either way

• Tested as one unit SMTP, IMAP, spam filtering, antivirus, webmail and administration are exercised together against real servers before an image ships. A version bump in one part cannot quietly break another.
• Backward compatible Your data and your configuration survive upgrades. We have not asked anyone to reinstall since 2014.
• No babysitting Upgrading is always the same thing: replace the container. No procedure, no migration script, seconds of downtime. We can do it for you.
• Monitoring included The server watches itself. If you want somebody else to be the one who notices, we can watch it from the outside and step in.
• Custom work is possible The whole thing is ours, so we are not waiting for an upstream project to accept a feature. Tell us what you need.
• Not a weekend project Shipping since 2014, 10M+ Docker pulls, and paying customers who have been with us for years.
