Hi,

I am newbie in the sendmail rule. I need to write a rule as below
requirement.

-- usera(a)abc.com can only send mail to usera(a)def.abc.com

Is it require to change the "check_compat" rule set ??

I am using sendmail 8.12.11

Any comments are appreciated.

Thanks.

Hi,

Thanks for your posting. I'm sorry that I haven't specified clearly in
the above requirement.
Actually, I also need to check....

1. Sender name and recipient name must be the same.
2 .All sender must send to a specific domain ( e.g @def.abc.com)

That is, each user can only send mail to one email address

Therefore, only accept the following mail....

usera(a)abc.com --> usera(a)def.abc.com
userb(a)abc.com --> userb(a)def.abc.com
userc(a)abc.com --> userc(a)def.abc.com ... etc.

Would you pls give suggestion ?? How to modify the above example to
fullfil this requirement ??

Many thanks.
