I've just encountered a problem with the HtmlMails sent by NodeInvite.

If I set the 'Site-Wide default MailSystemInterface class' (Site configuration - Mail System) to 'DefaultMailSystem' everything works fine, except that I don't get HTML-mails from node-invite. If I then set it back to 'HtmlMailSystem' only the last inserted e-mail-address in the 'Email Addresses for Delivery'-textarea gets the mail. This is due to the fact, that only this e-mail address is passed correctly to the mail system...

in mail.log i can see for the correct mail-address:

Jul 18 23:25:44 xxx-server postfix/smtp[9402]: 343C836AA491: to=, relay=127.0.0.1[127.0.0.1]:10024, delay=0.34, delays=0.02/0/0/0.32, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=09330-08, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 7F00836AA3FD)

for the other mail-addresses i get something like that:

Jul 18 23:25:44 xxx-server postfix/smtp[9401]: 2B76836AA439: to=<=?UTF-8?B?YW5kcmVhcy5yZW5uZXJAYmFsZHVyLXNlcnZlci5jb20N?=@xxx.com>, orig_to=<=?UTF-8?B?YW5kcmVhcy5yZW5uZXJAYmFsZHVyLXNlcnZlci5jb20N?=>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.25, delays=0.03/0/0/0.22, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=09372-04, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 6294436AA3FD)

I hope you see what I mean...something goes terribly wrong here :) The problem is, I'm not quite sure where the problem is coming from, because I don't use any other modules for sending out mails.

Maybe anybody out there with a similar problem?
