I am facing the following problem in cisco asa 5505 version 8 when clients are sending mails from inside to outside
a. Clients cannot able to send the mails to recipients ( say 200 ) at a time.
b. if they reduce the no: of recipients say 50 they can send
c. if we bypass the firewall they can able to send mail even to 4000 recipients at a time.
Can some help me on sorting out this issue
