[SOLVED] Imapsync: Auth [LOGIN]: 3 no cleartext login DISABLED

We have an old email server running Postfix/IMAP4, and new email server running Zimbra Network Edition under Ubuntu AMD64 OS.

I was trying to run imapsync to sync my old email box to new zimbra mail box. The command I type was:
./imapsync --nosyncacls --subscribe --syncinternaldates --host1 oldmailserver --user1 myaccountname --password1 mypasswd --host2 zimbramailserver --user2 myzimbraaccount --password2 myzimbrapasswd --noauthmd5

I have enabled clear text logins, but still received an error from my zimbra server, which is:
error login : [host2] with user [user2] auth [LOGIN]: 3 NO cleartext logins disabled

3 NO cleartext logins disabled
...propagated at /usr/bin/imapsync line 676.

tried the same flags but adding -ssl2 and then still get
Error connecting to host2:993:

Is there anything else I should enable or check?

Try restarting the Zimbra server.

I did it. But still didn't work. So I uninstalled Zimbra, made a clean installation again and enabled clear text login before I install imapsync. This time imapsync worked.... Thanks a lot for your information.

Used a script on the zimbra wiki to install imapsync. Was also having the same difficulty syncing mail.
...NO clear text passwords not...

After enabling clear text on Zimbra, I restarted the server but still it wasn't working.
I updated my perl installation, run the enable cleartext command and then restarted zimbra and everything worked just fine.

This is the command I used..
imapsync --buffersize 8192000 --subscribe --nosyncacls --syncinternaldates \
--host1 $host1 --user1 "$user" --password1 "$p1" \
--host2 $host2 --user2 "$user" --password2 "$p1" \
--noauthmd5

Got my scripts and instructions from the Zimbra Wiki. Thanks guys.
