ChrisP,
I re-ran my tests using your examples and it sort of works. The problem is that the rule appears to modify other parts of the header. Specifically, it appears to strip the white space character (in this case a horizontal tab) from the header. This results in the email client not being able to fully interpret the To header.
Example: "To:" header NOT changed by replace.
To: "someone@domain1.tld" <someone@domain1.tld>, "support@n2net.net"
<support@n2net.net>, "someone@domain2.tld" <someone@domain2.tld>
Example: "To:" header changed by replace.
To: "someone@domain1.tld" <someone@domain1.tld>, "support@n2net.net"
<support@n2net.net>, "someone@domain2.tld" <someone@domain2.tld>
Is there any way to prevent replace from mangling long header lines?
Thank you,
Jim L

Use this:
if (isin("to","support@n2net.com")) then call replace("to","*support@n2net.com*","%1support@n2net.net%2")
call replace("to","*support@n2net.com*","%1support@n2net.net%2")
end if
In brief:
1) replace needs 'call' in front of it.
2) don't use recipients, that is a loop for each envelope recipient, whereas you want to do this for the header which is not related to the recipients.
3) do it twice, so that it picks up two instances in the single header.
