[Techtalk] `TO:' header alias rewrite - Sendmail

[Nosferatu!!!]

Hi all,

I am having a little problem with my aliases in /etc/aliases file.


Scenario:

Say I have the following alias definition in /etc/aliases -

ruby:		rubidium at hotmail.com

Now, sendmail expands the "ruby" to the proper address in "RCPT TO:",
but, the "To:" header in the message still reads "To: ruby".

Its not a big deal for me except that "ruby" has Hotmail filtering
on that rejects messages whose "To:" header does not read as
"To: rubidium at hotmail.com"

Also, I want it to work this way only for selective aliases and not
for ones like

buddies:	aaa at hotmail.com, bbb at yahoo.com, ccc at rediffmail.com

I know I'll have to write rulesets for that, but, I don't have
access to the Bat book. Anybody feeling suicidal? ;) 

My sendmail.mc for Sendmail 8.9.3 looks like this 

divert(-1)
dnl This is the macro config file used to generate the /etc/sendmail.cf
dnl file. If you modify thei file you will have to regenerate the
dnl /etc/sendmail.cf by running this macro config through the m4
dnl preprocessor:
dnl
dnl        m4 /etc/sendmail.mc > /etc/sendmail.cf
dnl
dnl You will need to have the sendmail-cf package installed for this to
dnl work.
