Unable to send large files -- mailx

[Nayak's]

Hi Guys,
I am unable to send large files using mailx. There is no problem sending file sizes of 1-2 KB. But nothing more than that goes through.

thanks in advance

Where is it being stopped? Have you tried sending large files to yourself on HP-UX?

i can see it in the mailq. At the moment i am trying to send the files to myself

What is the O/P for below...

sendmail -v -d9.99 -d38.99 email_user < /tmp/file_name

To yourself on the local machine?

Hi,

Exactly what command you used.

Check the /var/adm/syslog/mail.log file for any messages.

Regards.

Shalom,

sendmail itself which is the default MTA for HP-UX does have some limits on attached filesize.

I believe this is done to prevent spammers from taking down an entire machine by clogging its /var directory with attachments.

The default limit is I believe 2 MB, although you can increase that by changing sendmail.cf or using sendmail macro compiles (much more human readable).

Hi Rasheed,
Here is the relevant output from the log. As you could see the smaller files go fine. It is only the larger files that get stuck

Did you try uuencode

uuencode file filename |mailx -s "uuencode" sanjaynaik@hp.com

[Dennis Handly]

>Yes i am trying to send the email to myself

But not to HP-UX on your local machine. It seems you sent it around the world. :-)

[Nayak's]

Sorry to confuse you Dennis,
I meant yes i am trying to send the file from the machine to my mailbox. Do tell me if that is not clear.

thankyou
sanjay

>i am trying to send the file from the machine to my mailbox

I was suggesting you only send the mail on a short hop (back to the same machine), only through HP-UX to see where the limits are.

Hi Sanjay

Try this

ux2dos /path_to/some_file | uuencode some_file.txt | mailx -m -s "MAIL FROM Someone" someone@somewhere.com
