ask about asa5505 smtp deny but exception for some application
Dear All, I recently modify the asa5505 config file, here is the orginal config file , its working fine , but you know recently the spammer is serious & I wana to block the smtp out , only the host 192.168.0.200 ( a exchange server ) can send email outside , and all workstations include 192.168.0.x /24 will be deny to send or telnet outside port 25 , then I make changes in the config, the changes is under the orginal config file ****
and then I found one problem,some workstations need to use a application need smtp also, the ip address is 22.214.171.124 255.255.255.x port 25 & 110
any sugguestion for the config if I need to modify in this case ?
the aim :
deny 192.168.0.x smtp but except 192.168.0.200 ( exchange server )
allow 192.168.0.200 smtp outside
allow 192.168.0.7 smtp & pop3 to 126.96.36.199
ASA Version 8.3(1) ---------------------------------------------------here is the orginal config, not have block smtp yet
