Hi Everyone,

The following feature request was received from a Debian user.


> The sudo() configuration file /etc/sudoers should accept a "mailfrom"  
> variable to specify the "From:" header for warning and error mail  
> generated by sudo().  Sudo already supports the "mailto" and "mailsub" 
> variables.
> Motivation:
> 1) This would provide a system administrator the ability to specify the 
> "From:" header in sudo() alert email using an address that does not 
> reveal names of any machines on an internal LAN that are generating the 
> email.
> 2) I found that sudo() placed the header "From: dduck" in email alerts 
> when user dduck failed to provide a proper password for sudo().  Some 
> SMTP servers may reject the email message with a 550 Error for not having 
> a valid "From:" address, e.g. [email protected]  To fight spam, more 
> SMTP servers are checking that the "From:" header at least includes a 
> valid domain in the address.  This would be also probably be more 
> consistent with RFC2822.
> I am using Debian GNU/Linux 4.1.1-21, kernel linux-image-2.6.18-5-686, 
> and libc6 version 2.3.6.ds1-13etch2.
