Universal email - not sending emails

Not sure what's happened here - this is a page I did for a client about a year ago.

It was definitely working back then, but he's been in touch to say it doesn't seem to be now.

So I was wondering if someone could have a quick look over the page to see if it looks right.

Unfortunately its using a private database, so I can't really post a link.

The old system had an option to buy a token for a tech to look at things - in this case I'd be happy to pay a nominal charge to do this.

I just don't really want to start tinkering with things, as I'm so sure it was working.

Coincidentally there was an SQL memory error on another search just the other day, that was resolved by adding

RLimitMem 128000000

to the .hcassess file.

So it may be some sql / server issue.

So if anyone at WA could have a look at the pages involved to test that they should be working, I would very much appreciate it.

Thanks.
