sending to multiple addresses

The attach_mailer_class seems to work fine when sending an email to a single address, but it fails the check_mail_address function when there are multiple addresses. With a previous version, it was working OK, but I see that all the calls to check_mail_address function from attach_mailer are commented out. I don't recall, but I guess I did that to get it to work. When I skipped the validation, I could pass it a string of addresses separated by commas and it would work fine. Are you supporting multiple addresses? If so, how do I get the address validation to work, or should I just continue to bypass that? Thanks.

hello,

I commented the validation in other applications I build to make it possible to add a string with multiple email addresses.

It better to send the mails in a loop for all email addresses.
