Migrating email from an email provider to a YunoHost instance
Documentation linked to YunoHost email.
Migration of emails from one server to another can be done with two recommended tools: ImapSync or Larch.
This tool must be installed on your desktop computer. The transfer method looks at this schema:
Old email server −> desktop computer with ImapSync or Larch −> new email server
ImapSync
Install ImapSync on your client computer by following this guide:
sudo dnf install imapsync # Under Fedora
Transfer emails from one server to another:
imapsync --host1 <domain/IP> --port1 993 --ssl1 --user1 <user> --password1 <password> \
--host2 <domain/IP> --port2 993 --ssl2 --user2 <user> --password2 <password>
Note that transfer settings --port 993 and --ssl are specific to YunoHost email server.
Larch
After beforehand installed gem, install larch on your client computer:
sudo gem install larch
Transfer emails from one server to another:
larch -a -f imaps://serveur_d'origine.org -t imaps://serveur_de_destination.org
For other types of transfer refer to Larch documentation.
