@eddowding If you like you can patch the file in /home/yellowtent/box/src/mail.js and systemctl restart box.

@girish WHOOP!!! Thank you!!

@necrevistonnezr I actually wrote a post about migrating email hosts using the imapsync tool that girish recommended, you can check it out here. Note that my post is a bit more extensive as I also migrated registrars and had other active emails there that weren't mine, so yours should hopefully be a bit easier than the whole tutorial!
