Is it syntactically correct to delimit multiple email recipients in the "To" header of an email with spaces only or do I need to use another delimiter (a semicolon or the like)?
Example (MIME data reads as follows):
Date: Mon, 04 Oct 2010 06:14:16 +0200 From: email@example.com To: firstname.lastname@example.org email@example.com firstname.lastname@example.org Subject: Test Subject
The above will be processed by many email processing applications, but I need to know whether it's correct according to standard (RFC). Unfortunately I didn't find anything useful on the internet so far.
Thanks a million for your help!
