And ... finaly I get it working ... almost.
How I did it?
First I made the change in the "org_alfresco_zimbra.
js" file. I changed the line 453 from:
--- cut ---
for each (var mimeType in AlfMimeTable.list ) {
--- cut ---
to next:
--- cut ---
for (var mimeType in AlfMimeTable.list ) {
--- cut ---
Then I run as zimbra user next command:
zmprov mc default zimbraProxyAllowedDomains "*"
And it gets work.
Here are some problems with attachements:
When I am trying to attach file which name contains white space or which name contains UTF-8 characters, the file fail to attach.
For this problem I would ask the plugin developer to help to solve this issue!
