The closest thing would be restricting mails based on message size but this applies to the entire mail and not the signature. https://www.ibm.com/support/knowledgecenter/SSKTMJ_8.5.3/com.ibm.help.domino.admin85.doc/H_RESTRICTING_MAIL_ROUTING_BASED_ON_MESSAGE_SIZE_STEPS.html You could open an enhancement request with IBM Support to request something similar with the mail signature. Thanks, Mark
