I am using mailx command to send a mail with attachment. It's working fine, but with attachment I am getting one extra attachment like (ATT00131.txt). I have tried to use unix2dos command also. But still I am getting the extra attachment.
what is your OS? My OS is sun. I tried the same program but I haven't get any extra <A* .txt> file. I attached .txt and .xls file, both os them I received as it is.
Instead of mailx you can try the attachunix command.
Usage: /usr/lbin/attachunix [-t letter body] [-s subject ] [-m mail address] <attached files>
