Sam,

a friend tried to sent the mail from his hotmail account and it was returned 
several times.
As this error prevents you from receiving the mail in the first place I have no 
idea if this happened just once or often.
On the other hand 100,000 bytes is a lot - and unless others are having the 
same problem I can probably ignore it.

Anyway, thanks for help and explanation!

Hi,

Courier couldn't receive a hotmail message due to the header size limit:

>Feb  5 13:56:27 linde courieresmtpd: error,relay=::: 
65.54.190.222,from=: 534 Message header size ? 
>exceeds policy limit.


Is this a common feature/problem?
Should I adjust the header size and if so where do I do this.


The most likely answer here is that Hotmail was hacked and is being used to  
send garbled spam.


You can adjust one of the two header limit parameters in the bofh file, man  
courier, and search for BOFHHEADERLIMIT.


But, really, do you really want to accept crap with >100,000 bytes in its  
header?

you can hard-tune this configuration option in source code. Note that it's
possible that message is misformatted. Last time I've been solving this
problem, a buggy PHP script was adding the same header for over 700 times...

If possible, look at the message at source server...
