請問,若是要多個寄件者的話,應該怎麼做呢?
我是一直出現這錯誤Caused by: javax.mail.internet.AddressException: Illegal address in string

andowson

寄件者只能有一個，可以透過Email類別的setFrom的method來設定，可接受三種參數呼叫方式:

setFrom(String email)

setFrom(String email, String name)

setFrom(String email, String name, String charset)

如果要收件者，可以透過Email類別的addTo的method來增加，類似setFrom有三種參數呼叫方式:

addTo(String email)

addTo(String email, String name)

addTo(String email, String name, String charset)

收件者可以有多個，只要連續呼叫多次的addTo即可(例如透過迴圈)或者先將收件者整理成一個清單(List)，再呼叫setTo一次設定好

setTo(Collection aCollection)

至於您的錯誤訊息，可能是charset編碼問題，也可能是其他問題，得看到程式碼才能得知。
