authentification problem with sendmail and smtp

[Adel ESSAFI]

Dear list
I have a problem with smtp and sendmail. My smtp requires a login and a
password. no ssl connection is required. The port is 25.
I have used this configuration below.


divert(-1)dnl

include(`/usr/share/sendmail-cf/m4/cf.m4')dnl
VERSIONID(`setup for linux')dnl
OSTYPE(`linux')dnl
define(`SMART_HOST',`smtp.gnet.tn')
GENERICS_DOMAIN(localhost.localdomain localhost)dnl
FEATURE(`genericstable')dnl
MASQUERADE_AS(`gnet.tn')dnl
FEATURE(masquerade_envelope)dnl
define(`RELAY_MAILER_ARGS', `TCP $h 25')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 25')
FEATURE(`authinfo',`hash /etc/mail/authinfo')dnl

in /etc/mail/authinfo I have put this line
AuthInfo:smtp.gnet.tn:25 "U:adel.essafi" "P:mypassword"  "M:LOGIN PLAIN"

However, when I send an email, I receiv an error message: authentification
failed. Could you help please.
Regards
Adel
