Up to now I have been using postfix as an
internal server at home
relaying messages from internal clients to my ISP, but also
receiving
mail on port 25.
Now my wife has an Android, I'd like to enable her to send mail
through
the server when out and about. With the options I have with the
ClearOS
front end, to allow user/pass authentication it sets:
smtpd_sasl_auth_enable = yes
smtpd_tls_auth_only = no
Unfortunately this opens up user/pass authenticated relaying to
port 25
as well as 587 and is vulnerable to to being brute forced
remove "smtpd_sasl_auth_enable = yes" from "main.cf" and add "-o
smtpd_sasl_auth_enable=yes" to the submission entry in "master.cf"
