E-mail support in CentricStor
Appendix
12.2 E-mail support in CentricStor
12.2.1
Sendmail configuration
sendmail
is started only if the configuration file /etc/mail/sendmail.cf exists. This file is
not generated, but under certain conditions it is modified to correct errors.
During installation a sample file is created under /etc/mail/sendmail.cf.sample which
can be used as /etc/mail/sendmail.cf. This file may need to be adapted.
In CentricStor systems sendmail cannot automatically determine the external name and the
customer domain. As a result, the file /etc/mail/sendmail.cf must be adjusted
manually as follows:
1. After the section
# my official domain name
# ... define this only if sendmail ...
#Dj$w.Foo.COM
you must enter the following lines:
Dw
Dm
Dj$w.$m
2. If the mail host (smarterhost) is not mail.
entry DSmail.$m must be altered accordingly.
12.2.2
Setting up the DNS domain service
If the host is not or not fully configured as a DNS client, the following message is issued at
startup during installation:
WARNING: local host name (....) is not qualified; ...
To ensure complete sendmail functionality, the host must be configrued as a DNS client as
follows:
–
The file/etc/resolv.conf must contain the following entries (the separator is the
tabulator!):
domain
nameserver
nameserver
The nameserver must be entered with the IP address.
