Values & Validation: email format

Password
Password of the email account from which the emails will be fetched.
Password field

Host
Type the name of the host of the email account.
Values: free string

Port
Type the port number.\ Default value is 993, which should be ok in most cases. Check with your administrator if this value should be changed.

Socket factory fallback
Default value is set to "Yes". This parameter sets the behaviour in case the socket used to connect the Nuxeo server to the email server fails to be created using the implemented socket factory.

Add all fields in https://doc.nuxeo.com/userdoc/nuxeo-imap-connector/#email-folder-parameters

This document type should be hidden from import, so, no Import layout needed.
