the ~ means if it is not from your servers it is also okay.
the - means ONLY from your severs.
The link I posted earlier (linuxbabe.com) had an interesting take on "~"
vs "-" and why the former is preferable:
If a multi-host (postfix) site receives your mail (like Google?) and it
gets relayed between their servers (perhaps main one is down for
maintenance), and the final server gets the mail from the backup, sees
"-", it may reject it.
Not sure if this is correct, but did cause pause for thought and am
considering changing "-" to "~" on my domains.
Your SPF "should" maybe say:
mimosa.com. IN TXT "v=spf1 +a +mx
+ip4:206.248.139.113 +ip4:98.158.128.23"
If I recall correctly, it's best to put IP addresses earlier in the list
to save DNS look-ups, saving a tiny bit of time.

True, and I agree it's best to include them to be as specific as
possible on the author's intentions, however the "+" is the default,
hence implied.
But, I agree, use them anyway.
