You need to remove the 'spamguardremovebeforesending' part of the address.
spamguardremovebeforesendingdeborah.obrien5@verizon.net Alternatively, try deborah.obrien5 at verizon.net
(remove the at and replace with @ and have no spaces between the number 5 and the word verizon - I'm being careful to avoid spam access to my e-mail address)
