SID-02170: Internal error when sending email to xxxx

Status:	Asked	TWiki version:	6.0.2	Perl version:	5.18.2

Hi all, I have created the TWIKI server. Web browser works fine but, when i try to register I get this error. Do I have to change any file permissions in the twiki server or change any configuration settings? as far as i read from other questions, i have changed the file permissions of .htpasswd file. I'm using the mail id that belongs to my company for SMTP mail id and password. The error message I found on the warning.txt ERROR: Can't send mail using Net::SMTP. 5.7.0 Authentication required

Can someone please help me out. I'm new to this TWiki installation.

Discussion and Answer

This error message indicates that your mail host ( configuration variable: {SMTP}{MAILHOST} ) only accepts mail from authenticated users, which is a usual countermeasure against bad guys who use unprotected mail relay servers for spam distribution.

I am not sure what "mail id" means in this context, but here's some guidance: In configure, you need to define values for {SMTP}{Username} and {SMTP}{Password} which are considered "valid" by your mail host. In corporate environments, servers which send mail often get their own "username" and password to distinguish them from human senders, and to avoid having to change the password every other week. In a Microsoft Active Directory, these are usually called "machine accounts". Your IT admins should be able to help you with that.
