[Users] get_hdr_field: bad to header...

[Lars Sundqvist]

Hello,

We have a few hundred users registered to a openser we are running and 
everything works fine, however i get som error messages in the logs I 
would like to get rid of...

//sbin/openser[28867]: ERROR: get_hdr_field: bad to header

Anyone has a clue what I can do to debug this to find out where the 
request are coming from or what can be done to stop the invalid(?) 
requests from being processed and clutter my logs?

Thanks
