When there is an unusual activity detected in your account via IMAP, your account may be blocked for a period of 5 minutes to 5 days, for IMAP Access, depending on the type of activity detected. The account will be unblocked automatically. You can contact support (at) zohomail (dot) com for details.
If you are sending emails using an IMAP client, the sent messages appear twice due to a configuration setting in the IMAP Client you use. When a message is sent through the Zoho SMTP server, the server places the sent message in your Sent folder. The IMAP client which you use, again copies the 'Sent' messages to the server, making it duplicates. Some clients have option to avoid this behavior.
