Hello,

I try to send a e-mail message, but it keeps on failing.

The exact same settings in outlook work perfectly.
What is my mistake?

The SMTP username is an e-mail address of 44 characters
The password  is 9 characters.

::oSmtp           := SmtpClient():New("smtp.somexternalserver.com",587," mydomail.nl",oLogWriter,nLogLevel)
If ::oSmtp:Connect("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa@mydomain.nl","PWDPWDPWD")

I am 100% sure the username and password are correct.
Below the log
What is my mistake ?

Regards,
Jack Duijf

Jack,

>What is my mistake?

Never post real login names and passwords in news groups, even if they are 
base64-encoded and didn't work for some reason. 

>The SMTP username is an e-mail address of 44 characters

This doesn't match the indicated connect string. What ASINET sent was:

AUTH PLAIN recreatiepar01@recreatieparkdegroot

Instead, using your (example) login name and password, it should have been:

AUTH PLAIN aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa@mydomain.nlPWDPWDPWD

or actually, base64 encoded:

AUTH PLAIN YWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFAbXlkb21haW4ubmxQV0RQV0RQV0Q=

Obviously, the login name and password that were actually sent are not only 
too short, they also don't contain the "@mydomain.nl" domain part, as they 
apparently should. 

You may want to check what was actually used in the :Connect() method, as 
the string that was actually sent is so different to what your login name 
and password should be, that it seems unlikely that this is an encoding or 
similar issue with the ASINET SMTPClient class.

Hope this helps, even if this response is a little bit late.
