The only options to imap_open are all documented here:
It does give you quite a bit of flexibility, but I'm afraid I don't know 
anything about problems with Zimbra in particular.

However, a quick bit of Googling produced these:

So the answer appears to lie in using at least "/novalidate-cert", and 
possibly by actually doing a POP authentication rather than an IMAP one, 
which the options let you do (see the 1st link above).

> I think I've narrowed the issue slightly but I still can't authenticate with IMAP. I see that Zendto is using the imap_open command in the code. I found that some people have had issues connecting to Zimbra's IMAP using imap_open. However, none of the workarounds I've seen help me. Most people fixed the issue by adding /novalidate-cert at the end of the IMAP server name.
