I am looking at doing a Zimbra to Zimbra imapsync. When I put in the imapsync code, I am immediately getting " error conecting to imap.host.com:993" yet, I can make a connection to it through Outlook (on port 993) without an issue and do a telnet to the imap.host.com 993.

/usr/bin/imapsync --nosyncacls --syncinternaldates --host1 imap.host.com --user1 user1 --password1 password --ssl1  --host2 localhost --user2 user2 --password2 password --noauthmd5
I know I am probably missing something simple, its been a long day...
