sendmail && SMTP AUTH: question about /etc/mail/auth/client-info file

[Matthias Apitz]

Hello,

Because I was forced by my ISP to do so, I have configured successfully
as described in the FBSD docs the sendmail with SMTP AUTH;

one question remains: the required file /etc/mail/auth/client-info has 
the line:

    AuthInfo:smtp.1blu.de "U:root" "I:YYYYYYYYYYYYY" "P:XXXXXXXXXXXXX"

where the I: value is the userID given by the ISP and P: its password;
what does the U: value is good for exactly? thanks in advance

	matthias
