Net Lib SMTP Error

[BobsYourUncle]

Hi All,

I'm using Net lib (v1.3) to send an email (smtp). It works fine when I send through Gmail, but I get the following error when I try and send through a different email provider (BTInternet.com). All the ports and login details are definitely correct.

Anyone got any ideas?

Did you try turning off the UseSSL, set it to False and see if it works.

 

[BobsYourUncle]

UseSSL has to be set (according to their documentation). If unset then the connection is just dropped. Looks like Net Lib does not support the protocol for the initial handshaking...?

 

[margret]

I use SMTP in a few apps and on different devices and I have not had any that decline to work.

 

[BobsYourUncle]

Thanks Margaret. Maybe it isolated to this one provider, but in the UK they are one of the biggest, so I suspect other providers will also have this problem.

I have the same problem using hotmail (live)
SMTP work with gmail and yahoo so far but not with Hotmail,

anyone knows of a workaround ?
is it a bug ?

TESTAPP: errror sending mail:javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x2bba50: Failure in SSL library, usually a protocol error

thanks

This error means that the server is using a non-standard protocol. Make sure that this server supports SSL.

Its microsoft man that's their moto (non standard)

Its not working without ssl
