Hi All,

Can any of you provide info on following issue :

I created API to put mail on external SMTP server. On running the code following issue has been observed:

Do you have any resolution about the exception.

Hi All,

As per the project requirement, API needs to configure in such a way that i should trigger mail to external domain i.e gmail, rediff or yahoo mail ID. To incorporate the requirements following code developed at developers end:

Not sure what going wrong.

Things tried at my end:
Updated Jmail 1.4.4
JAF 1.1

Can any body provide view on it?

Try to check "Is there any authentication required for the SMTP Mail Server", specified in code.

If yes then try to put

Transport trans = ses.getTransport("smtp");

trans.connect("<SMTP Host>","<SMTP Auth User Name>","<SMTP Auth Password>");

for more details please follow the link
