Dovecot provides a master login (a master user name and password that can log into all user accounts).
I've setup Dovecot as per: http://wiki1.dovecot.org/Authentication/MasterUsers
Here's my problem.
The only way I can authenticate successfully is if I try to authenticate through telnet twice.
$ telnet mail01.server.com 143
Trying 10.10.10.10...
Connected to mail01.server.com.
Escape character is '^]'.
* OK Dovecot ready.
1 login user@server.com*master my_password
1 NO Authentication failed.
1 login user@server.com*master my_password
1 OK Logged in.
imapsync (the tool I need to use to migrate over emails from Dovecot to Zimbra) won't work.
$ imapsync --nosyncacls --syncinternaldates --host1 mail01.server.com --user1 user@server.com*master --authmech1 PLAIN --password1 my_password --host2 mail02.server.com --user2 user@server.com --authmech2 PLAIN --ssl2 --password2 user2_password

Will try to use PLAIN authentication on host1
Will try to use PLAIN authentication on host2

Host mail01.server.com says it has CAPABILITY for AUTHENTICATE PLAIN
Error login: [mail01.server.com] with user [user@server*master] auth [PLAIN]: 2 NO Authentication failed.

If I try without the master user it works. Please help.
