When a time-driven Input Agent of type "Mail" retrieves the contents of a mailbox, it is forced to take all emails in the mailbox. This happens regardless of whether the emails are processed by the current profile. Afterwards, a processing profile has to be found for each email.

Something similar applies to the input agent of type "SMTP". An email sent to via SMTP must first be accepted. If an email has been received, a processing profile has to be found for that the email.

Best practice

Due to these circumstances, it is advisable to use a dispatcher profile for the sake of clarity (even though you do not have to).

For the Input Agent "Mail" (POP3(S), IMPAP(S), X.400), i.e. if you actively pick up emails from a server, there is an explicit mechanism for this with the distribution rules. Important note: If you want to test a profile with such an Input Agent (manual restart), it must be active so that emails are not moved to the Unresolved area. In addition, you should switch to Trigger/another profile in the Times tab (other time specifications only work if the profile itself is not entered as the processing profile).
For the Input Agent "SMTP", (acts as an email server), the profile that uses this Input Agent should forward the emails to other profiles via Message. See section Profile chains.
