Top Forums UNIX for Dummies Questions & Answers Can't configure sendmail to send mails to external SMTP Server Post 302480756 by methyl on Wednesday 15th of December 2010 05:37:57 PM

Further to DGPickett we must ensure that mail server is in /etc/hosts AND the the fully qualified host name of the host server is in /etc/hosts too.
Mentioning the same server twice is deliberate.
It doesn't have to be ".com", this is just an example.

Code:
# Example /etc/hosts with example IP addresses
100.100.100.100 myserver.mydomain.com myserver
101.101.101.101 myemailserver.mydomain.com myemailserver


Hope this helps.

SENDMAILCONFIG(8)					      System Manager's Manual						 SENDMAILCONFIG(8)

NAME
sendmailconfig - configure sendmail for Debian systems SYNOPSIS
sendmailconfig [--no-reload] DESCRIPTION
sendmailconfig is used to simplify the configuration of sendmail(8) for use on Debian systems. In the simplest case, you may run this program to (re)configure sendmail for your Debian system at any time. It will modify the file /etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf. For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invokations of sendmailconfig will preserve these changes provided they are made at the end of the file. Normally sendmailconfig will ask if you want to reload sendmail after making changes to its configuration. The --no-reload option will avoid this question. FILES
/etc/mail/sendmail.mc sendmail m4 input to generate sendmail.cf /etc/mail/sendmail.cf actual sendmail configuration file /etc/mail/sendmail.cw names for which we will accept mail in the standard configuration /etc/mail/sendmail.ct names of trusted users in the standard configuration SEE ALSO
