deals only with errors that happen once the email is received.
Whereas this FAQ http://www.livejournal.com/support/faqbrowse.bml?faqid=115
Where are my comment notification emails?
includes details about why LJ emails may not be being received.
Which means when someone isn't getting the validation email, we direct them to the FAQ on notification email problems. This is a tad silly.
It'd be nice if the first FAQ said something like:
If you are not receiving your validation email then please see the following for information on why you may not be receiving emails.
It still is a bit of an awkard fit, but it's better. And the only other way to clear it up is to change the second FAQ< and we don't want to cut out the bit about checking that you set yourself to receive notification emails.
You could change the second FAQ to Why aren't I receiving LiveJournal emails and then say, if you aren't receiving notification emails for comments then....
Whatever, but something should be done.
