But it might be a hassle if you aren't already using procmail. ~/.procmailrc: :0 fw | /home/me/bin/fix-mail-headers-filter /home/me/bin/fix-mail-headers-filter: #!/usr/bin/env perl use warnings; use strict; # Modify headers if needed (e.g. "reply-to:" to "Reply-To:") while (<>) { # Skip to the following trivial loop after headers print, last if /^$/; # Replace lowercase at start of word before colon with uppercase s/^([^:]*)\b([a-z])/$1\U$2/ while /^[^:]*\b[a-z]/; print; } # Jut print the rest unchanged print while (<>); The above was barely tested. Don't use it without testing it on lots of existing mail (one message at a time - see formail(1)) until you are sure that it works. And note that it doesn't convert any uppercase to lowercase, only the other way around. cheers, raf
