Hi, When I am sending bulk emails to customers from my Dazzle/Endicia account with Thunderbird Mail using a google apps account, domain name @paradiseintranet.com I receive a pop up error message. I've sent an email to myself and a couple other people and we receive the message which is great but I do not understand why this error message keeps popping up. I receive multiple messages when I send multiple emails. I hope this makes sense.... EEK! Thanks, Samantha Outgoing server (SMTP) error occured while sending mail. The server responded: 4.7.0 Temporary system problem. Try again later (WS).p199sm2150346itc.2-gsmtp. What is this and what does it mean?
