The sending of e-mails automatically is dependent on various factors. Please check the following points. If the problem persists, please contact our support department.

First, check if the mail server is set up correctly. You may find the guidelines for configuring the mail server from the Wiki pages for testing the e-mail configuration and client profile characteristics. Send a test message after the mail server settings have been adjusted (see Screenshot).

Should the problem persist, follow the following steps:

Please check if there is an entry for the intended e-mail in the mail queue. The mail queues can be viewed in the admin-client under the tab labeled e-mail queue (see Screenshot). email_queue.jpg}} If the mail queue contains an entry for the mail that was to be sent, continue and check the next step. If there is no entry in the mail queue, please contact our support team.

Check if the sendAllDelayedEmails timer was set and started. The list of created timers can be found in the admin-client under the Timer tab (see Screenshot). timersendalldelayedmails.png

Check if the option Message per E-mail Preferred under Task Message Mails in the client profile is activated (if there is a check-mark) (s. Screenshot). clientprofil3.png
