Redmine

Hello.

Is there possible to create multiple e-mails for each user? Divided by commas for example.
Why it's needed? As for me - I have an Redmine installation, and emai2SMS gate. So, new issues from Redmine can be transferred directly to cell phone and to e-mail.

Unfortunately, I'm not experienced in Ruby, so I cannot help with any.
May be it is duplicate, but I'm found nothing about.
May be some things to do that already exists? Please tell me, or just put a link to docs.
Thanks at all!
