If you are willing to push a different (customized) notes client mail template to your users, then you can simply change the formula behind the &quot;CopyTo&quot; field on the Memo form. &nbsp;In the onChange event for JS or the Input Translation for Formula, you could instruct it to strip out any groups and place them in the &quot;BlindCopyTo&quot; field instead. &nbsp;Just some thoughts. &nbsp;If this is what you are looking to do and willing to do, let me know and I can help further.<br />

Good Luck.

I have a situation where a local user sends an email to an external user and CC's a Domino group comprised of additional external (i.e. someone@somedomain.com) users. &nbsp;The issue is that the user that receives the email is able to &quot;reply to all&quot; and send email to the external users within that group. &nbsp;Obviously, if the local user BBC's the group, the external recipient cannot reply to all. &nbsp;I'm wondering is this default design for Domino or is there a way to change this like I could with Exchange. &nbsp;

Lotus Domino Groups and external recipients

Lotus Software produced the Lotus 1-2-3 spreadsheet program, and later developed Lotus Notes, a groupware and email system. Following its acquisition by IBM, the Notes and Domino client/server collaborative platform were expanded to include functions such as email, calendars, to-do lists, contacts management, teamrooms, discussion forums, file sharing, microblogging, instant messaging, blogs, and user directories. IBM also release SmartSuite, a comprehensive office suite, and followed that with Symphony, unrelated to the Lotus suite of the same name.
