the existing command was like

uuencode purge_files_2018-07-07.log.gz  purge_files_2018-07-07.log.gz   | mailx "Subject:Purge file";echo -e "\nHello Team,\n\nPlease find the attached list of files which have been purged -s [email protected]

now I have replaced it with

echo "Subject:Purge file";echo -e "\nHello Team,\n\nPlease find the attached list of files which have been purged.\n\nRegards,\nAxiom Tech Support";/usr/bin/uuencode purge_files_2018-07-07.log.gz purge_files_2018-07-07.log.gz)|/usr/sbin/sendmail -t "[email protected]"

So my question is why mailx is not working but sendmail is working. actually i will have to change in multiple scripts so I am seeking the solution.

Mailx upgrade switched it to use MIME as mail content instead of plain text. Your email client does not recognise uuencoded content within MIME.

You can stop using uuencode and switch to

mailx -a <filename>
