Comment	> When chosing to have an email remindet sent for an event, the email > address that a user enters into the form is not checked. If the > input is in fact not a valid email address (e.g. just the username > with no domain), this leads to problems at the time the reminders are > to be sent, with the site administrator receiving emails from the > cronjob running horde-alarms. The invalid input should be caught at > the time the user fills out the form so that they can enter a valid > email address instead. > > I see two ways in which the form used for entering an email address > for reminders to an event could be improved: > > (1) Append the default domain to unqualified addresses just like IMP > does. This may be a bit difficult to do since the domains that would > need to be appended are only set in IMP's backends.local.php, so that > info might not be available to Kronolith. Maybe the form should be > re-displayed in this case with a note to the user to make clear that > the email address has been changed automatically. > > (2) Do at least some basic checking of user input, i.e. validate that > it is a syntactically correct email address. For instance, an input > such as "a@b@c" should never be accepted.
