warning: mail() [function.mail]: SMTP server response: 501 5.1.7 Invalid address in C:\Websites\lexpublib.org\www\includes\mail.inc on line 193.

I'm not sure what is causing this error or how to fix it. I've been reading some online about 501 7.1.7 and there appears to be a problem with the Sender information send to our SMTP server. We are using Exchange 2007. All other system mail is going to correctly. However I had a similar error using the WebForm module and was able to correct this by using the SMTP Authentication Support module.

Does this look like a server configuration error or a module problem with Simplenews, or something else?

I have resolved this issue. I had failed to set the sendmail_from = mailing address variable in my PHP.ini file.

Although this is not a subject a lot of users are involved with, perhaps you want to write a few lines on this in the Simplenews handbook: http://drupal.org/node/197057
