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"
