cron not sending external mails
This script is to send a email if the IP adress is active
when i run this script it is working and sending emails to external users in different domains, but when this script is scheduled in a cron it is unable to send the emails
Code:
 
#/bin/sh
ifconfig -a | grep 192.168.0.1
if [ $? == '0' ];
then mail -s "subject" mail.domain.com < /home/user/mailmessage.txt
fi

So i used a while loop avoding cron, Below is the code, This is able to send the emails,

Code:
#/bin/sh
while :
do
ifconfig -a | grep 3.229.224.157
if [ $? == '0' ]
then 
   mail -s "CRITICAL!! PAN Credit Application Load Balancing Has Failed Over to MYUKSLCAP2LB002" -c \
  emailaddress@fqdn.com < \
   /home/smg_prod/mailmessage.txt
fi
sleep 60
done

But for the same code why it is not able to send emails when set via cron, checked cronlogs and found no errors, cron is executed as schedules, also checked messages no errors found

gpg-mailkeys

GPG-MAILKEYS(1) 					      General Commands Manual						   GPG-MAILKEYS(1)

NAME

       gpg-mailkeys - sends emails containing keys to their owners

SYNOPSIS

       gpg-mailkeys id...

DESCRIPTION

       gpg-mailkeys  sends  the owners of the keys listed on the command line a mail each, containing their public key. After signing, you can use
       this tool to send everyone the new signatures they just got.

       If you're interested in encrypting the signature before it's sent, in order to verify that the associated address actually belongs  to  the
       key owner, you should check out caff

OPTIONS

       None

ENVIRONMENT

       NAME	    Set the name to use when sending messages

       EMAIL	    Set the email address to use when sending messages

       SUBJECT	    Set the subject of the messages you send

       TEXT	    Set the body text of the messages

       SENDMAIL_ARGS
		    Set  arguments to pass to /usr/sbin/sendmail. This can be useful to set credentials in order to authenticate to an smtp server
		    when using ssmtp for example.

FILES

       The behavior of gpg-mailkeys can be updated through some files available in the user home directory.

       Thus, ~/.gpg-mailkeysrc allows the user to overwrite the default value for the above environment variables, and any  text  in  ~/.signature
       will be appended to the end of the body text of the message.
