Emailing System Backup invalid BODY

RouterOS Beginner Basics
1

ive tried a few script to email myself a system backup and the rsc file sends fine but the bin files errors with invalid BODY

here is one of the script i have tried

#
# Created Jotne 2020 v1.0
#
# Takes two different backup and send then to email
#
# backup.rsc readable backup
# Certificates, the Dude and Usermanager are also NOT exported or backed up fully and should be backed up separately.  Can be used to restore config to different routers
#
# backup.bin binary backup
# Binary backup that can only be used to fully restored the same router.
#

:local email "xyz@gmail.com"

/export file=backup
:delay 2s
/system backup save name=bin
:delay 2s
:local date [/system clock get date]
:local time [/system clock get time]
:local info [/system identity get name]
:local serial [/system routerboard get serial-number]

:local files "backup.rsc,bin.backup"
/tool e-mail send to="$email" subject="Mikrotik: Backup $info $serial" file=$files body="Automatic Backup of $info $serial at $date $time."
:delay 20s
/file remove backup.rsc
/file remove backup.bin
:log info message="Backup router=$info serial=$serial ok"

Works for me. What exactly is this error and where it comes from?

Thanks for your reply, I just realized one thing i hadn’t tried, I was using an IIS SMTP Server which is the one I was getting the error from so I tried relaying through a Linux SMTP relay I have and it worked

i am getting the same error what could be the problem?

the script is working on selective routers

May i know what’s the invalid body mean?

Tested with other email clinet to send email with the same email server, it works fine.
