[C++] E-mails versenden

jokey2 · 26. Juni 2008

versuch's mal mit

Code:

 send("mail.web.de","Absendername","Anonymous@ano.de",arr[0].c_str(),
       "Betreff","Nachricht");

Die Funktion akzeptiert keinen Datentyp std::string als Parameter.

Ich würde die Schnittstelle der send-Funktion ändern in:

Code:

void send(const char *smtpservr, const char *fromname, const char *fromid, const char *toid, const char *subject, const char *message);

Natürlich sowohl in Deklaration als auch in der Definition. Da Du in der send-Funktion keine der übergebenen Daten änderst, ist das der einfachste Weg.

liegt das an dem SMTP server von web.de oder liegt das an mir
in der "empfaenger.txt" sind die adressen aufgelistet....
...
empfaenger1@web.de
empfaenger2@t-online.de
empfaenger3@arcor.de
...usw....
