The server response was: Sender address is not valid for your login. Check your email program settings.".

Hi,

This is caused by the fact that SPAM protection is enabled on the SMTP server.
And this should stay like this.
The SMTP server does not want to rely the message as it things that you want to propagate spam.
For Example:
you work in the office and your domain is NAVOffice.com.
You will be able to connect to SMTP server NAVOffice.com and send emails with your username
user@NAVOffice.com.
You client domain is NAVClient.com
If you try to send an email from your Office and to use NAVClient.com SMTP server, you will get this error message. The reason is that you are not part of the NAVClient.com environment e.g. your IP address.

In other words if it works for your company credentials it will work fine for clients when you are at clients premises.

I hope this helps.

Thanks.
