Dear all, First of all, let me thank you for the excellent quality of the list, for me it's a pleasure to follow it, really. Now for the question. Is there a difference between defining the from variable and using a my_hdr From: command to define the From header ? I RTFM, but however can't figure out the answer. However I noticed the use_from variable, which I guess has a link with the question. Help of any kind sincerely appreciated. Thanks in advance, Sébastien.
