今天在log檔中發現了這個警告訊息:
2009-09-27 23:55:37,822 WARN [SummaryJob] - net.jforum.exceptions.MailException: com.sun.mail.smtp.SMTPSendFailedException: 550 5.4.5 Daily sending quota exceeded. 36sm5053156agc.20
Google搜尋了一下
Gmail Daily sending quota exceeded(google),發現用 Gmail 一天只能發送給500個人,看來要拿來發電子報還是有限制。
Google will temporarily disable your account if you send messages to more than 500 recipients or if you send a large number of undeliverable messages.
