E-mails received via the Input agent "SMTP" for which no active Profile can be found are discarded and lost. For e-mails with multiple attachments, this applies to each individual attachment.
However, you can also specify that such e-mails will be moved to the “Unresolved” area instead. This is done in the configuration file ./etc/startup.xml (Default: false).
IMPORTANT: This entry only applies to the input agent "SMTP", but not for the scheduled input agent "Mail". However, there, this can be set directly in the GUI.
<Set name="saveUnknownMails">true</Set>If files are moved to the "Unresolved" area, an e-mail notification can be sent. See Warning for non-assignable input data.
NOTE: A detailed description of how to process e-mails can be found in Input agents that are forced to receive all the data.
