Hello, I am trying to gauge how many sites use SMTP verification.

If anyone can point me to sites with any relevant (reliable) stats.

Assuming there is no reliable data, rather than pollute the list with
heaps of yays or nays if people would like to email me any info they can
I will summarise back to the list..
i.e.

How many domains: 3 (I would like to be able to summarise by domain)
SAV in use: yes/no
SAV Mode: Sync (no SMTP response unti verify completes)
SAV Mode: Async (SMTP response 4xx's until an async vrfy comes back)

Of course, any additional info is welcome and will only be included
in output if if it can be summarized/anonamised.

A web form is at http(colo slash slash)caren.ddns.me.uk(slash)sav.pl

Thanks,
Jacqui Caren

p.s I will read this thread so feel free to coment here - please be
gentle :-)
