sendmail woes

[Matthew Carpenter]

(Hacked out of a message from my Sendmail guru)

relay-domains
mydomain.com

local-host-names
mydomain.com

virtusertable
@mydomain.com    %1 at internalserver.mydomain.com
abuse at mydomain.com       sally at internalserver.mydomain.com
customer.service at mydomain.com    jake at internalserver.mydomain.com
customer_service at mydomain.com    jake at internalserver.mydomain.com


Sendmail Hack
Modify the cd /usr/local/sendmail/smmta-8.10.0/cf/mailer/smtp.m4 file to 
add the sendmail rule

#       Added to fix INTERNALSERVER virtuser problem
# user at internalserver.domain.mine ==> user at domain.mine
R$* < @ internalserver. $* > $* $: $1 < @ $2 > $3
#       End INTERNALSERVER hack

immediately after the 

#
#  envelope recipient rewriting --
#  also header recipient if not masquerading recipients
#
SEnvToSMTP=21

header lines, and before the

R$+                     $: $>PseudoToReal $1            sender/recipient 
common
R$+                     $: $>MasqSMTP $1                qualify unqual'ed 
names
R$* < @ *LOCAL* > $*    $: $1 < @ $j . > $2

rules in that section. Load, Save, and Deploy config.

The hack strips the LNOT28 out of the address when it forwards the
virtuser stuff to a back-end host. Without it you get addresses like
me at internalserver.mydomain.com upon delivery.



Hope this helps
