Using PHP to clean up my client list.

[jeddiki]

Hi,

I have a client list which I have not sent out any
email to for about a year, and I sent an email last week.

Now my emails have an opt-out link which keeps the mysql
database clean.

But, how do I clean out the the non-deliverables?

From my mail out ( of c.5000 emails), I got about 450 bounces.
Obviously I don't want to keep sending out to emails to
non-existent addresses so I want to somehow access those addresses and
take them off of the clients table.

The reason that I know that I get the bounces is because I get
an email back to my sending email address saying that it was not
deliverable.

I have complete access to my server and I have been looking
for the right files to use but I can not find them.

My server runs the Postfix mail server and I use WebMin to admin it.

Any ideas where I can find this information and how I can get it into a
table ?

Thanks

All I can think of off the top of my head (mainly because I don't know how to capture email addresses from a bounce) is to either get the active users to click an "I'm still active link" which will update a time (and then you can delete those with the time longer than a year or something) or to manually do it.

However, there has to be a way to run something in the mail server to make a list of bounce's email addresses, and then remove the record from the database... Just not sure how.
