Sending mail with SMTP from task scheduler

Posted on by jgaztanaga 225

Hi everyone,

I've created a function that send an unknown number of mails to customers. What I've seen, is that yesterday, I need to send 20 mails, and only 15 were sent. The last 5 haven't been sent. When the task ends, we should also send a mail with the summary of the sent mails, but it hasn't been sent either. Does the SMTP have any typ of limitation?

Thank you very much

    Hi,

    Maybe your Mail-server has a limitation.

    Include an error-handling to see if you receive an error back.

    Maybe your NAV did send 20 mails, but the SMTP-server only accepted 15 and refused the remaining 5.

    It may happen sometimes due to security reasons, spam etc.

    Really appreciate your answe. I control the errors this way:

    MailSent := mailSMTP.TrySend;
    IF NOT MailSent  THEN BEGIN
      lShipmentHeader."Notification failed" := TRUE;
      lShipmentHeader.MODIFY;
    END;


    After the execution, I can see that no ShipmentHeader."Notification failed" is marked, so I can assume that NAV has generated the mails correctly...

    Looks like an issue with the limitation you are talking about

    Thanks Hannes.

    Tonight everything worked correctly. I've introduced a SLEEP sentence of 15 second between every e-mail creation, and the error was solved.
