Bootstrap via Blat

[ingar]

Hi

I am using the notification function in Legato to send bootstrap file to an email address, the way I have inserted the command is as follows:

blat - -s "Group Status" -t +TLLegatoadmin@tubelines.com -server tlqewfc020001.tubelines.com:25 -u username -pw password

when running this command it dosn't send anything and when I run the same in command prompt it prompts me for an entry and sends the email.
If I modify the command to look like this:

blat c:\cb.txt -s "Group Status" -t +TLLegatoadmin@tubelines.com -server tlqewfc020001.tubelines.com:25 -u lega3652 -pw password

it sends it.
Any help will be appretiated. Thank you
