e-mails including urls with colons inside are not rendered correctly as links by the webmailer I am often using to read these message, and likely others, too. Thus I suggest to generally urlencode colons in the automatically generated urls put in e-mails, which at least does not hurt.
Well, urlencoded colon does make it harder to read them, but I don't know if it's a problem.
