I cannot send email to multiple recipients from FileMaker 13 using Apple Mail 7.3 (Mac OS X 10.9.4). This method has worked since 2008, but has broken since the upgrade to Mavericks. I have tested the script under FM 13 and Apple Mail 6.6, and it still works. I am using AppleScript to send the email, but I get the same results if I send using FMP's Send Email script step.
I use a plain text field to store email address(es). The field is pre-populated with one email address using a Set Field command. Users may click a button to add addresses, or type them in by hand. From the script, addresses are appended with a comma-space between addresses (e.g., email@example.com, firstname.lastname@example.org).
Mail.app treats the text from the field as one large address, regardless of the comma. If only one address is in the field, the email goes out without a problem. The specific error is:
This error occurs whether I use AppleScript or Send Email methods.
I have tried using a semi-colon as delimiter. I have also tried coercing the text field into an AppleScript list.
In Mail.app, if I delete the space between the addresses and add it back, the addresses are recognized as separate addresses!
How can I get Mail.app to recognize the text string for what it is?
I recognize this may be a Mail.app problem, but I am hopeful I have just missed something obvious in FMP.
Glad to provide script steps if needed.
