New page

Situation: You want to use the sendmail '''nullclient''' FEATURE, but you want to use the alias database and/or .forward files.

In this example, I'm running sendmail 8.11.7p3+Sun on a Solaris 8 SPARC system.

== Enabling the alias database ==

Given my existing '''sendmail.mc''' file:

VERSIONID(`$Header: /var/cfengine/masterfiles/solaris/etc/mail/RCS/sendmail.mc.mm,v 1.6 2008/11/07 19:44:56 hutchib Exp $')
OSTYPE(`solaris8')
define(`confFALLBACK_MX',`host.example.com')
FEATURE(`nullclient',`host.example.com')

And given '''/usr/lib/sendmail/feature/nullclient.m4''':

# This is used only for relaying mail from a client to a hub when

undefine(`ALIAS_FILE')
'''define(`MAIL_HUB', _NULL_CLIENT_)'''
'''define(`SMART_HOST', _NULL_CLIENT_)'''
'''define(`confFORWARD_PATH', `')'''

'''MASQUERADE_AS(_NULL_CLIENT_)'''
'''FEATURE(`allmasquerade')'''
'''FEATURE(`masquerade_envelope')'''
'''MAILER(`local')'''
'''MAILER(`smtp')'''

I replace '''FEATURE(`nullclient',`host.example.com')''' with the above lines in bold from '''nullclient.m4'''.

My '''sendmail.mc''' now looks like:

VERSIONID(`$Header: /var/cfengine/masterfiles/solaris/etc/mail/RCS/sendmail.mc.mm,v 1.6 2008/11/07 19:44:56 hutchib Exp $')

define(`confFORWARD_PATH', `')
ifdef(`confFROM_HEADER',, `define(`confFROM_HEADER', `<$g>')')
define(`_DEF_LOCAL_MAILER_FLAGS', `lsDFM5q')
MASQUERADE_AS(_NULL_CLIENT_)
FEATURE(`allmasquerade')
FEATURE(`masquerade_envelope')
MAILER(`local')
MAILER(`smtp')

Next, I substitute '''`host.example.com'''' for '''_NULL_CLIENT_'''.

I also have to add the '''A''' flag to '''LOCAL_MAILER_FLAGS''' above to enable the alias database. From '''op.pdf''':
'''A''' Look up the user (address) part of the resolved mailer triple, in the alias database. Normally this is only set for local mailers.

My '''sendmail.mc''' now looks like:

VERSIONID(`$Header: /var/cfengine/masterfiles/solaris/etc/mail/RCS/sendmail.mc.mm,v 1.6 2008/11/07 19:44:56 hutchib Exp $')
OSTYPE(`solaris8')
define(`confFALLBACK_MX',`host.example.com')
define(`MAIL_HUB','''`host.example.com'''')
define(`SMART_HOST','''`host.example.com'''')
define(`confFORWARD_PATH', `')
ifdef(`confFROM_HEADER',, `define(`confFROM_HEADER', `<$g>')')
define(`_DEF_LOCAL_MAILER_FLAGS', `ls'''A'''DFM5q')
MASQUERADE_AS('''`host.example.com''')
FEATURE(`allmasquerade')
FEATURE(`masquerade_envelope')
MAILER(`local')
MAILER(`smtp')

We now essentially have a "nullclient" configuration that uses the alias database.

== Enabling .forward files ==

To enable .forward files, the following changes need to be made to the above '''sendmail.mc''' file:

* '''define(`confFORWARD_PATH', `')''' needs to be removed.
* The host cannot use a mail hub; '''define(`MAIL_HUB','''`host.example.com'''')''' needs to be removed.
* The '''w''' flag needs to be added to '''LOCAL_MAILER_FLAGS'''. From '''op.pdf''':
'''w''' The user must have a valid account on this machine, i.e., getpwnam must succeed. If not, the mail is bounced. See also the MailBoxDatabase option. This is required to get “.forward” capability.

'''sendmail.mc''' now looks like:

VERSIONID(`$Header: /var/cfengine/masterfiles/solaris/etc/mail/RCS/sendmail.mc.mm,v 1.6 2008/11/07 19:44:56 hutchib Exp $')
OSTYPE(`solaris8')
define(`confFALLBACK_MX',`host.example.com')
define(`SMART_HOST','''`host.example.com'''')
ifdef(`confFROM_HEADER',, `define(`confFROM_HEADER', `<$g>')')
define(`_DEF_LOCAL_MAILER_FLAGS', `lsADFM'''w'''5q')
MASQUERADE_AS('''`host.example.com''')
FEATURE(`allmasquerade')
FEATURE(`masquerade_envelope')
MAILER(`local')
MAILER(`smtp')
