Hello Guys,
I am scratching my heads over 3 days and couldnt find answer yet. So, you
guys are my last hope now. We are running exim , IMAP and mysql on one
box. I must have to accept
local_domains and local_hosts in ACL. But still anyone can send email to my
domain users via telnet 25 other than relay. How can I solve this issue.
My configuration is as
acl_check_rcpt:
accept hosts = :
accept domains = +local_domains
endpass
message = unknown user
verify = recipient
accept hosts = +relay_from_hosts
accept authenticated = *
deny message = relay not permitted
For example my virtual domain is abc.com
>From outside:
telnet mymailserver 25
helo test
mail from:[EMAIL PROTECTED]
250 OK
rcpt to:[EMAIL PROTECTED]
250 Accepted
data
354 Enter message, ending with "." on a line by itself
hello
.
250 OK id=1K51XZ-00084q-SF
so, I can write script that can generate fair enough spams. How can we
overcome on this? Any help would be appreciated.
Thanks,
Farhan
