Question Email Routing


Hi,

I want to route of my ougoing mails from my LINUX red hat6.0 mail servers.

At present all my ougoing mails is connected to an VSAT which trnsefers all my emails through that INTRANET line. I am thinking to have a check on the all the ougoing mails so that I can route according to my wish. I have a extra ISDN dial-up connection which I want to use for the mails which do not belongs to my organization. I have my own domain eg example.com, so my collegues have an email id as rajesh@example.com. So when a mail is addressed to a person belonging to my organization eg: rohit@example.com, I do not want to do anything I want it to flow as I flows through my existing VSAT line, from my sendmail file. If a mail is addressed to a unknown person such as mohit@hotmail.com, then I like to invoke my ISDN dial-up connection to sending it.

Queries
1. Tell me how to go about it?
2. I want to know how you access the recipent address when an user sents it.
3. What actually happens, when an user composes a mail in its MUA and click on the send button.
4. When it connects to the sendmail file.
5. How can I link my script to sendmail.cf file.
6. Where Shall I place my script.

I will be really grateful if you can please help me out with my questions.

I am expecting a prompt answers to my queries

Regards
Wish U Happy New Year

sendmail and routing

Hi ,

look mandal sendmail is not concerned with selecting the method for connecting to external world ..... according to rule sets if it discovers that a mail does not belong to local domain then it selects the non-local mailer ( ie;smtp ) ... the os takes care of it so u could try out the s/w calles iproute2 ( used for QOS ) which does the traffic shaping things ..... read the docs about it.

Got my point ?

About the other things u better read the numerous online docs available.

Regards,
Xanthium.
