Question about one of those services that validates email addresses on
the fly when you fill in a form...
There is one (Briteverify) which seems to fail email addresses at our
postfix server for an unknown reason.
I put my email in the form (it's used by a local food delivery
service), and in the background I see this on my server:

...and the webpage pops up an error about it being an invalid email
address. I can use my work email address and it validates and I can
order dinner :-D
Has anyone else any experience on what exactly they are looking for to
actually validate? They don't actually appear to test for my email
address, rather the non-valid recipient address which is rejected,
then postmaster which passes early tests but is disconnected by the
client before being fully sent.
Simon.
