Cannot send email, receiving emails though

Error when trying to send emails:
Unable to connect SMTP server:smtp.gmail.com Reason:Authentication failed:535-5.7.8 Username and Password not accepted. Learn more at535 5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 ng13sm9741318pdb.82 - gsmtp

I updated the password for one of the associated emails this morning. Works b/c we are receiving emails since the password change. Cannot send email though, receive the error above. Are others having same issue?
