It seems some outbound email from Scalix to various clients are not being rendered correctly by the other clients. Some emails can't be read by Blackberry users, I have trouble reading some in Thunderbird.
I'm guessing it's related to the content-type formatting of the email but that's just a guess.
I'm also trying to get all the info regarding the problem. I susspect it just with attachments as well.
I'm running v.9 of Scalix community.
