If recently wanted to migrate my e-mail from Surftown to
my VPS at ThrustVPS. I wanted to avoid doing this with
e.g. Thunderbird, since I would then be limited by my very poor upload bandwidth
of 512 kBit/s. Luckily imapsync came to the rescue.
imapsync is a Perl script that lets you synchronize IMAP mailboxes
incrementally while keeping flags such as read, unread, deleted and so on. The
script also supports TLS, so it should be able to connect to most servers. Like
all good things there is a Debian package
for this utility too.
In my setup, I was running imapsync from my VPS, so the destination server was
localhost.
source: mail9.surftown.com:143 with STARTTLS
username1 / password1
authentication: PLAIN
destination: localhost:993 IMAPS
username2 / password2
authentication: PLAIN
$ aptitude install imapsync stunnel4
$ stunnel -c -f -d 1143 -r localhost:993 -P ''
$ imapsync \
--host1 mail9.surftown.com --user1 username1 --password1 password1 --tls1 --authmech1 PLAIN \
--host2 localhost --port2 1143 --user2 username2 --password2 password2 --authmech2 PLAIN
