Depending on which SMTP server you are using, you may be able to have all
employees everywhere use the same outgoing SMTP server config by using
authenticated SMTP (Possibly on a port other than 25). Doing this would
make generating an SPF record much easier.

SPF does NOT necessarily make other people see your legitimate email as less
likely to be spam. It does, however, make spammers who forge your domain
possibly appear as more likely to be spam. It all depends on how you craft
your SPF record.

This is a problem, which is why I recommend having your own outgoing SMTP
server for all to use.

If you did this, and sbcglobal.net had an SPF record of their own (they do
not), then you could have included their record in yours, but since they do
not have an SPF record, you would be forced to guess all the various
outgoing SMTP servers they use, which would be next to impossible.

Either one of these is probably the most appropriate for you.
Since you have your own domain (Basically required for SPF anyway), someone
has to be hosting your email unless you are forwarding the various addresses
to other email accounts. That hosting company might offer outgoing SMTP
services as well, which may be the best choice for you.
Hope this helps...
