Problem with postfix attachment

[ansan]

I need to send mail with a file attachment from linux system to my mail id

while using the command

mail -a filename mailid

In the webmail the attachment is blocked
the file size is 396K

I need the file as attachment in the mail.Please help me in doing the same

there are multiple possibilities why if fails,
assuming you OWN the server, have access to

/etc/postfix/main.cf
and all relevant config files

check for allowed/disallowed file extensions
check if attachments are allowed
check for file size limits

I use your a.m. procedure sometimes, but with a different syntax:

cat /server_path_to_file.txt | mail -s "your subject line" recipient_email_address

Good luck
