I'm not getting the second two lines.

How "should" one correctly get the subject ???

What I did was in my .procmailrc file
SUBJECT=`cat | grep Subject:`

So this resulted in only the first line and not grabbing the additional 2
lines.

Is there a way to correctly get the subject that I have not found?


You'll need to grab the line that starts with "Subject:" and then 
continue grabbing lines until you find one that doesn't start with 
whitespace.  I don't think you can do this with grep, but you should be 
able to do it with perl, sed, or awk.

sounds like your issue is procmail then...  I just used your exact

Procmail unfolds headers. Could it be the logging that's truncating the 
subject? Where is that "Assigning" output coming from? You could dump the 
SUBJECT variable to a file to see what it really thinks is in there.

There's supposed to be a "null" line between the structured (header)
text lines and the rest of the body. The "Subject:" is generally the
last of the structured text lines, so you should be able to start
your read with the "Subject:" tag and continue reading until you hit
the "null" line.


No, there is simply no rule nor evidence that the subject header line is 
or should be the last of all header lines. Typically you see it 
somewhere within the mail's header.

A "Subject:" line is just a structured text line in the message body
and MTAs (e.g., sendmail) don't do anything differently with it than
any other line in a message body. The max length is 998 "characters".


No, the subject of a mail message is a defined field and part of the 
message header, not the body of the message. Just see RFC 5322. Message 
header and (optional) body are separated by an empty line. While there 
are specific rules for message header fields there are (nearly) none for 
the character flow of the mail body (MIME RFCs aside). The 998 character 
limit per line applies for both the header and the body.



I suspect that your MUA or more likely procmail is where the
truncation is taking place. I just did:

   /bin/mailx -s"... 200+ character subject ..."

on a C6/sendmail machine and it worked fine.


That turned out to be the case as the OP didn't cover folding of long 
header fields (RFC 5322 2.2.3).

are you saying the subject is 3 lines (not one long line that wraps
over 3) before you try to send it as email?

if so you need to strip out the newlines (or CR/LF) or whatever is
there as linebreaks.

Have a look at the "tr" command, possibly the -d option.

echo "now  
is  
the  
time" | tr -d "\12\15"

prints "now is the time" but note that there is no newline at
the end of the string, so you'd need to add one back.

if you do this, you get the trailing newline, though this looks
pretty weird:

/usr/bin/echo -e  `echo "now 
is 
the 
time" | tr -d "\12\15"` 

good luck!

so, your issue is something specific on your configuration. hmm, c7's

you'll need to be a whole lot more specific.   I've seen emails with 
stupidly long subjects, one message sent to a list recently had the 
entire message body pasted onto the subject.


Where are you running into this issue, how is it manifesting itself, 
what software is involved (email client, email server, email list server?)


I see you're using gmail, are you sure this problem isn't specific to gmail?

There needs to be more context. Where and how do you face the limit? 
Client-side or on the mail transport? The RFC defines a limit for mail 
headers and the subject is one of them. Would be very strange to hit 
that though.
