i am sending mail to list of users, i am sending mail using mailx utility
mailx -s "$SUBJECT" "$TO" < $FILE
its working fine with valid emails, but problem is that i am getting dead.letter file when i tried to send to mail id like adffadf , it string not a valid email,
expected - i want this dead.latter must not be occur even user having anything for email ID.
like abc@gmail.com, abc@def.cc, adffdfs
The man page for my mailx says a lot of things about set nosave and so on, but they don't seem to work. The only way to stop your dead.letter file growing I have found is to replace it by a link to the special file /dev/null.
rm ~/dead.letter
ln -s /dev/null ~/dead.letter
