From 3 days ago I have a new zimbra, last version. Everything work fine, except when some account try to connect to my zimbra. Always this give message unable to connect with server. In firewall all is same, with the previous installation of zimbra this works, even Blackberries could send emails, but now nothing of this is working.
I have try configure my account with others email clients like Thunderbird and the connection is able to IMAP and POP, also SSL, but from any smartphone no.
Somebody have any idea to help me solve this?
Thank you to all.
By the way, I'm in Chile.
