using a header file in sendmail command

[cawthor]

How can I create my entire mail item in a file, and then send it via sendmail? Eg: I have a txt file containing all my mail info, To:, From: Subject: body...etc. I thought I could use the '-t' flag to pull all this info, eg:

$ sendmail -t mailitem.txt

However, I get the error :

No recipient addresses found in header

even though I have a 'To: aaa@aaa.com' line in the file.
Any ideas?

If your From, To, Subject, etc fields are away from the margin, sendmail seems to have this problem. Put them at the begining of the line without leaving any spaces and it should work.
