I had best luck using
Code:
imapsync --nosyncacls --syncinternaldates --user1 [username] --password1 [password] --user2 [username] --password2 [password]
Although the shell batching listed in the README file with imapsync...tweeked just a little produced great results:
created file.csv with content like:
Code:
username1;password1
username2;password2
username3;password3
for all my users...
then put this script at the command line
Code:
{ while IFS=';' read u1 p1; do
imapsync --nosyncacls --syncinternaldates --user1 "$u1" --password1 "$p1" --user2 "$u1" --password2 "$p1"
done ; } < file.csv
