Signature file issue

[ruggb]

up until the other day there was no problem.
After MUCH anguish I have discovered that I have 3 maybe 4 systems that won't send email via Outlook. The problem being associated with the signature file. It does not get to recipient if there is a 909 or 919 area code in the phone number in the signature.

signature file mail sends mail gets to recipient mail forwards
None yes yes yes
w/919 or 909 yes no no
w/212, 828, 333, etc yes yes yes
w/ just the # 919 yes yes yes

there is a 919 in a web link but that appears not to bother it.

When I fwd or reply mail it bounce back saying bad address
