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 same 
box. I must have to accept local_domains and local_hosts in ACL. But still 
anyone can send spam 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 testmail from:[EMAIL PROTECTED] 
OKrcpt to:[EMAIL PROTECTED] Accepteddata354 Enter message, ending with "." on a 
line by itselfhello.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.
 
Note: Before We were having separate SMTP and POP servers so we had different 
exim.conf for SMTP and POP. For SMTP there was no 
 
relay_domains and in POP there was no relay_hosts and it woked well. Thanks, 
Farhan
