That's really odd, I didn't have any problems at all at that stage - Do have more than one domain to test with, out of interest?I've given up, I finally got it to accept the changes I made to my domain records and then it wouldn't let me add an email address. Any email address.
Ahhh!No worries, totally fair! The lamiral.info site is the author of the imapsync project for what it's worth but yeah, I run imapsync on my own server, far quicker and easier to do a batch of accounts in one go!
