E-Mail-Service - Sending Setup

Maximum e-mail size

Here, the Maximum e-mail size can be specified. If the field is left empty, the size of the e-mail will be ignored. In the second column, the required units can be selected.

By default, 10 MB is predefined as the maximum size. This corresponds with the expected computer network norm for the maximum message size (e.g. preset value by Postfix or Microsoft Exchange Server). In general, it should only be modified when you’re certain that the potential recipients can receive messages of this size.

Maximum number of e-mails per session

Here, the Max. number of e-mails per SMTP session can be constrained. If there are several mails to be sent at the same time the smtp session will be terminated after reaching this limit. In the next transit a new smtp session will be created for the sending of the e-mails. The waiting time between the two transits of the sending loop is defined by the de.uplanet.lucy.sendmail.sleepInterval property (default : 1000 ms ).

Archive sent e-mails

If the setting Archive sent e-mails is selected, then sent e-mails will be stored in an archive file.
