How to create a new IMAP INBOX subfolder via command line on Plesk for Linux?

Answer

The example below demonstrates how to create a folder named newfolder for mailbox [email protected]

1. Connect to the server over SSH

2. Check what IMAP server is used:

   # command -v doveadm >/dev/null && echo ‘Dovecot’ || echo ‘Courier IMAP’

3. Create the mail folder:

   If Dovecot is used on the server

   Create the folder using the doveadm utility:

   # doveadm mailbox create -u [email protected] -s INBOX.newfolder

   If Courier IMAP is used on the server

   1. Download the attached script into the server: 

      # wget https://plesk.zendesk.com/hc/article_attachments/360012292139/courier_imap && chmod +x courier_imap

   2. Run the script and specify the domain, mail account, and the name of the subfolder that needs to be created. For example, for [email protected]:

      # ./courier_imap
      Enter the domain name. For example, “example.com”:
      example.com
      Enter the mail account (without the domain name), for example “email”:
      email
      Enter the name of the new folder to be created:
      newfolder
      /var/qmail/mailnames/example.com/email/Maildir/.newfolder directory created successfully
