I am trying to make sure my mail server is secure. I belive I already enabled pop3s and imaps so that it uses SSL, and therefore encrypting user passwords.
I can also do the same thing with sendmail when I want to send mail from my mailserver.
However, I need to have outside domains be able to access sendmail to relay to me, right? I unfortunately get this error when I try to send mail from a different account to my mail server:
Relaying denied. Proper authentication required.)
Is there something that I need to allow other domains to send mail to me without authenticating?
I think these are the important settings I have in my sendmail.mc file.
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
Any help is appreciated, thanks
