發送郵件報錯說明

發送郵件 假設發送人的郵箱username與郵箱password都沒有填寫錯誤：假設報：參數或變數中有語法錯誤。 server響應為:mail from address must be same as authorization user錯誤，問題可能出在authorization user  沒授權。假設是QQ郵箱。那麼僅僅要進入QQ郵箱。QQ郵箱：設定---賬戶  找到POP3/IMAP/SMTP服務  都開啟。這時候發現能夠發送郵件了。

假設報：SMTP server要求安全連線或client未通過身分識別驗證。

server響應為:Must issue a STARTTLS command first. 可能出現的問題是發送郵件的serverport（smtp.Port）配置錯誤。 比如：smtp.Port = 25

假設報：命令順序不對。

server響應為:Error: need EHLO and AUTH first ! 非常有可能是寄件者郵箱的username寫錯了；比如：（smtp.Credentials = new NetworkCredential("郵箱的username", "寄件者郵箱password");

假設報：參數或變數中有語法錯誤。 server響應為:mail from address must be same as authorization user  非常有可能是寄件者郵箱的password錯誤了：比如：（smtp.Credentials = new NetworkCredential("郵箱的username", "寄件者郵箱password");
