Notification mail problems

On my aC installation, I had to apply the following modification indicated at: http://www.activecollab.com/forums/topic/840/3/ Motherwell suggests: "1. Open /library/swift/lib/Swift/Stream 2. Go to line 370. 3. Replace: implode(', ', $this->getTo($string)), With str_replace("\n", '', implode(', ', $this->getTo($string))), The newline character in the to field stuffs everything up, and taking it out solves the issue." After applying this change, notification mails were sent out, without this hack, no notification mails were sent out. The test mail however has always been working. (NOTE: This applies for the current version of aC)
