Ok - I'm a little confused by SPF records. So - help me out :)
Let's say I set up a pretty strict set of SPF rules on my domain. Will that have any impact upon my ability to send mail from various locations via thundbird, outlook, etc?
I wouldn't think so, correct? Or - am I wrong? Would a fairly strict set of SPF rules confine me to only being able to send mail from specific locations via a normal email client?
