Re: [exim] authenticate * not work

i discover that SMTP fixup is on when connecting to port 25 but not
another port i open (1025)

# port 25

ehlo mail3.techsoft.com.hk
500 unrecognized command

# port 1025
ehlo mail3.techsoft.com.hk

but port 1025 still requires password in SMTP session when sending
mail to domains that are not 1 of my virtual domains. :- (

any help would be very appreciated.
