Sendmail / SMTP Auth
I have set up an RH 9 server that is a mail, dns and dhcp server.
I've got dns and dhcp set up ok but I am having trouble with sendmail and SMTP auth.
I want local users AND external roaming users to be able to sned/rcv mail via SMTP auth (using login to SMTP feature on most MUAs)
I followed the instructions here to set up SMTP auth: joreybump.com/code/howto/smtpauth.html and it seems to have gone smoothly. However I keep getting this error when I try to send mail from the MUA:
550 5.7.1 <email@example.com>... Relaying denied. IP name lookup failed [10.0.0.150]
10.0.0.150 is the IP of the local machine, granted via dhcp. Google searches suggest that I should be adding some blcok of IPs to a relay list, but that doesn't make any sense...I want any IP to be able to use this thing as long as they authenticate via smtp auth.
I got to work by dnl'ing this line:
define(`confAUTH_OPTIONS', `A p y')dnl
I hope I still have a secure sendmail setup???
i THINK i may have it working...
and follow it...
it APPEARS to have worked...
Another fix is to use pmpass, once a user POP3 auths, it will allow that user( actually, that IP) to relay for a certian amount of time. It has worked very well for me for over a year now.
