Migrating the sendmail Configuration File
Migrating the sendmail Configuration File
Beginning with the earlier HP-UX 10.20 release, the format of the
sendmail configuration file /etc/mail/sendmail.cf changed from the
version 1 format to the version 6 format. You cannot use a pre-10.20
version (that is, version 1) of the sendmail configuration file with the
sendmail included with HP-UX 10.20 and later. This section discusses
the methods of migrating a version 1 sendmail configuration file to the
version 6 file format. Note that you need to migrate the configuration file
only if you are updating your sendmail software from a pre-10.20
version to the version included with HP-UX 10.20 and later.
The /etc/mail/sendmail.cf file that is installed with the sendmail for
HP-UX 10.20 and later contains a default configuration that can be used
with HP-UX 10.20 and later. The script for installing Internet Services
on HP-UX 10.20 and later moves an existing /etc/mail/sendmail.cf
file to /etc/mail/#sendmail.cf, so you will still have the original file
for your reference.
NOTE If there is an existing version 6 /etc/mail/sendmail.cf file, then that
file is not overwritten by the script. If the
existing/etc/mail/sendmail.cf file is not version 6, then the file is
copied to /etc/mail/#sendmail.cf and a version 6
/etc/mail/sendmail.cf file is written. In either case, a sample version
6 configuration file can be found in
/usr/newconfig/etc/mail/sendmail.cf.
There are two methods of migrating your configuration file:
• Make any modifications that you need to the
/etc/mail/sendmail.cf file that is installed with HP-UX 10.20 and
later. This method is recommended where you have minimal
site-specific changes to the sendmail.cf file.
• Use the convert_awk utility to convert the old (pre-version 6)
configuration file into a format required by sendmail for HP-UX
10.20 and later. Note that while the resultant file is usable by the
10.20 and later sendmail, it does not allow you to use the format and
options available with the 10.20 and later sendmail.cf file. For this
reason, you should use convert_awk only if your old (pre-version 6)
