SingleLineFromHeader
Strip newlines from From: headers V8.8 and later
Lotus Notes’ SMTP mail gateway can generate From: headers that
contain newlines and that contain the address on the
second line:
From: Full Name
<address>Although this is legal per RFC822, many MUAs mishandle
such headers and are unable to find the address. If
your site suffers from this problem, you can define
the SingleLineFromHeader option using one
of these forms:
O SingleLineFromHeader=bool ← configuration file (V8.8 and later) -OSingleLineFromHeader=bool ← command line (V8.8 and later) define(`confSINGLE_LINE_FROM_HEADER', `bool') ← mc configuration technique (V8.8 and later)
The bool is of type
Boolean. If it is true,
sendmail will convert all
newlines found in a From: header into space characters. If
it is false, sendmail will
leave all From:
headers as is. The default for the
mc configuration technique is
false.
The SingleLineFromHeader option is safe.
Even if it is specified from the command line,
sendmail retains its special
privileges.
