mailman: send error 550 5.0.0 access denied


hi all...
in addition to samba...i've been setting up mailman for users webmail in my redhat 7.1 machine..took quite sometime to configure it and all...i tested my webmail today by opening my mailbox and composed an email for a friend in the network. Then i came across this prob: When i tried to email it, i got this message:

send error: 550 5.0.0 access denied

i teared up some hair looking about for the solution (since i'm not that well-informed about sendmail),tried adding entries in sendmail's access file, and then in relay-domains file..but to no avail. Finally i added this entry in /etc/hosts.allow after getting some hints on the net:

sendmail : ALL

that magically solved the problem! But i'm still pretty much in the dark about this...is sendmail protected by tcp-wrapper?I thought i only had to do this with the pop3 daemon.(I also have the entry popper : ALL in /etc/hosts.allow)I know this is a dumb question, but what i understood before was that only services in xinetd.d were protected by the wrapper (which is obviously wrong now, ha ha).I noticed that in redhat 6.X, i didnt have to put the sendmail : ALL entry...

i hope somebody can explain this to me..i'm a bit confused

I've had the same problem, and have been trying to figure it out for the past couple of hours! If anyone can explain, I'd love to hear it!
