When I change my email address to use "mail.com" as the destination, koodo will not send mail to my email address.
I've had a few people argue that mail.com is not a valid destination. If that's what you think then I invite you to go to mail.com and open a free account. I also know that some servers block "mail.com" because they think it's spam or something nasty.
Also under conversation type why not a "Fix me" or "Not happy" or perhaps "displeased"
