Send email to provider other than Google

[Tech500]

Please add an example for using another email account other than Google. Emailing and SMS text work great with dedicated Gmail account; thank you for the library code.

Had trouble understanding blog post: https://www.mischianti.org/2020/06/16/send-email-with-attachments-emailsender-v2-x-library-esp32-and-esp8266-part-2/

EMailSender(const char email_login, const char email_password, const char email_from, const char name_from, const char* smtp_server, uint16_t smtp_port);

When compiling; this line produces error: "expected unqualified-id before 'const'"

Maybe something I am overlooking; have not been successful in resolving this issue.

Hi Tech500, I think you must post the code you can try to execute to debug It.

But you can find the sendgrid provider management in this example https://github.com/xreef/EMailSender/blob/master/examples/EMailSenderArduinoMegaUIPSendgridTest/EMailSenderArduinoMegaUIPSendgridTest.ino

How do I correct?

250 Identification error (501 Syntactically invalid HELO argument(s))

My code:

`/*

EMailSender emailSend("", "", "", "", "mail.mw.net", 465); //Will this wotk; SSL/TLS port?

uint8_t WiFiConnect(const char nSSID = nullptr, const char nPassword = nullptr) { static uint16_t attempt = 0; Serial.print("Connecting to "); if(nSSID) { WiFi.begin(nSSID, nPassword); Serial.println(nSSID); }

uint8_t i = 0;
while(WiFi.status()!= WL_CONNECTED && i++ < 50)

    Serial.print(".");

    Serial.print("Connection: TIMEOUT on attempt: ");
    Serial.println(attempt);

Hi Tech500, I think your provider don't like the custom string on HELO command, you must check what kinf of string It expect and set It with this command.

emailSend.setPublicIpDescriptor("");

you can have this problem also if you don't use the provider line.
