sometimes when i reply to emails sent to my 700p (verizon) i get an error that reads: 473 (persons email address) relaying prohibited. you should authenticate first.

has anyone else seen this? how do you fix? sometimes, i'll soft reset and it sometimes alleviates it.. other times, i get rid of the quotes in the name (since my email populates the persons name and email address).

any better ways to solve this issue?
