[msmtp-users] credentials rejected with gmail

["rahed h" <raherh@...20...>]

Hello,

my relevant part of msmtprc.txt on windows is

account default
host smtp.gmail.com
auth on
domain gmail.com
user 
xxxxx@...20...
password xxxxx
port 587
tls on
logfile ~/.msmtp.log

When run from a command line, I get

msmtp: authentication failed (method PLAIN)
msmtp: server message: 535 5.7.1 Credentials Rejected

msmtp version 1.4.9

Do I miss something? I'm sure my credentials are ok.

Thanks Radek
