1.) Intrusion Defender -> Mail Firewall -> Configure Mail Services -> SMTPI Configuration -> Maximum Recipients Per Message
2.) Not sure if you mean a Stand Alone Secure Web Delivery Server or an Advanced Encryption Server (IronMail/SWD). In both cases though the configuration is under the encryption tab.
1- I configured SMTPI option already - set min number : 25
But I sent mail test: Cc for 28 recipients - Seem IronMail - split message from 1-24. All the recipient still recieved message.
2- I meaned IronMail/SWD - But when user try to connect: SecureEnvelope.html can't connect that link. Although SWD link configured in DNS server.
I tailed log from IronMail: SWD service: File not found
Thanks for any helping.
