Tim,
Not a good idea. If you write this patch, it shall not be included
into the Toaster.
Qmail gets a lot of security by not allowing certain characters. For
example, any e-mail address that contains a "." is stored in the file
system as a ":" because the period is a file system navigation
character.
Thanks,
Erik

Hi,
The toaster seems to be more restrictive than the current SMTP
specification. RFC 2821 (page 37) only specifically prohibts ASCII
characters 0 through 31 and characters greater than 126 from the name of a
mailbox.
As a long term solution, couldn't we modify the "C" code (specifically the
function check_sender_address_format) to allow any character in the ASCII
range 33 through 126. We could then use the badmailfrom control file to
filter out sender addresses that contain characters that are undesirable. A
single line with an explicit set of characters could be used - e.g. [
,;:"'`&%\$\^\{\[\(\|\)\]\}\*\+\?\\].
I could be missing something but I think that this will allow each site to
customize as required without rebuilding the "C" code and without losing any
functionality. I'd be happy to make the C code changes if this make sense to
everyone.
Regards,
Tim

Yeah, you will need to edit the C code before compiling it.
