SMTP SSL Issue

We have been running SMTP succesfully with PB12.02.  Recently we upgraded servers and now SMTP does not want to send e-mails externally

from the log:

of_SendMail Start: 10/14/2015 14:50:20

220 JARUXXX.jaru.com Microsoft ESMTP MAIL Service ready at Wed, 14 Oct 2015 14:50:20 -0400

EHLO WS91

250-JARUXXX.jaru.com Hello [1.1.1.1]

250-SIZE 37748736

AND MORE.......

MAIL FROM:<HelpDesk@jaru.com>

250 2.1.0 Sender OK

RCPT TO:<lmobradovich@gmail.com>

550 5.7.1 Unable to relay

Is there a way to manipulate SSL?

Thanks in advance

    I am not an Exchange expert but I am pretty sure that there is a Relay option in Exchange that needs to be set. I think the default was changed in newer versions of Exchange. The new default only allows you to send to internal email addresses.

      You are correct about the relay and to protect ourselves we open a new conector assigned to only the PC that sends the external emails, with an alternative port and secure authentication.

      Thank you very much.

    Hi Luis;

      Its pretty hard to comment on your problem as you have not really provided us with a lot of information. Can you tell us ...

    1) What mechanism you are using for SMTP interaction?

    2) How are you calling this from PB?

    3) What new O/S did you upgrade to?

    4) Is this a real server?

    5) Can you Ping the email server from your server?

    6) Exactly what release and build of PB are you using (12.02 is not a valid release)?

    7) Is your server real or virtual .. bitness?

    8) What email server are you using?

    etc

    Regards ... Chris

      H Luis;

        I would then contact the author of the code  - Roland Smith - at Topwiz and see what he says.  😉

    Hello Luis,

    According to the doc, error message "550 5.7.1 unable to relay for" is thrown when you try to send an email to an invalid email address or if you need to authenticate before sending an email.


    Try switching to SSL/TLS in the mail account settings of the client to resolve this error.

    HTH,

    Jacob
