I note that
http://www.ietf.org/rfc/rfc2368.txt which has been around for 12 years now states the email addresses should be comma-separated.
From he first couple of pages of the RFC, I learn that the example that I posted ought to work.
RFC 2368 has been superseded by 6068 in October 2010 which advises against repeated use of
cc headers as some mail clients don't handle them all; but it does not change or relax the use of a comma as the address separator.
it states clearly with example:
Code:
<mailto:addr1@an.example,addr2@an.example>
is equivalent to
<mailto:?to=addr1@an.example,addr2@an.example>
is equivalent to
<mailto:addr1@an.example?to=addr2@an.example>
From a personal preference, I wish that the default behaviour of the lds site was not to support a non-compliant piece of software whose use legal is limited to those with 83 dollars to spend on it, but rather by default supported all the many standards compliant email programs, most of which are available at low cost or no cost.
