DNS settings for SPF records with "redirect"

This question is about publishing SPF records in our DNS. We currently send mail from two places: an MS Exchange server, and an online app. The website sends mail through our ISP's SMTP server.

Our current TXT record is:  "v-spf1 redirect=exchangeserver.com", where "exchangeserver.com" is the domain of our Exchange provider. I would like to integrate the domain of our ISP into this record, as it is also sending mail on our behalf.

Question 1: do I create another separate TXT record for our domain, or add new details to the current record?
Question 2: does the "redirect" exclude directive exclude any other additions to the current record?

I would like to do something along the following lines and want to know if this is valid:

"v=spf1 ip4:IP-of-ISP redirect=exchangeserver.com"

Thanks!

Q1: No you can only have 1 entry
Q2: No you cannot use redirect= with any other parameter.

Since you are using redirect= then you can change that to an include= which has the same effect but allows you to have additional entries.

So you could use :-
"v=spf1 ip4:IP-of-ISP include:exchangeserver.com -all"

If your ISP publishes a SPF record then you could use include: for that instead.
