Email accounts all working fine until today. Am now receiving the following error message when trying to send an email:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: * OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ STARTTLS AUTH=PLAIN] Server ready proxy1.mail.iad3b.rsapps.net.

This email account is working fine on another computer running Thunderbird.

Any and all suggestions are welcome.
