---------------------------------------------------------------------- aaron - 05-Aug-05 01:09 CEST ---------------------------------------------------------------------- Same thing as bug http://www.dbmail.org/mantis/bug_view_advanced_page.php?bug_id=0000169: we're being a bit restrictive about validchars. This should probably be changed, since nobody's made any arguments not to do so. ---------------------------------------------------------------------- aaron - 05-Aug-05 01:10 CEST ---------------------------------------------------------------------- Also the same as bug http://www.dbmail.org/mantis/bug_view_advanced_page.php?bug_id=0000179. ---------------------------------------------------------------------- idk - 05-Aug-05 02:36 CEST ---------------------------------------------------------------------- Yes, I found validchars in lmtp.c, characters "|", "," and "?" are invalid characters in range http://www.dbmail.org/mantis/bug_view_advanced_page.php?bug_id=0000032-http://www.dbmail.org/mantis/bug_view_advanced_page.php?bug_id=0000126. But according to RFC 821, invalid char in local-part of sender/recipient addresses is "," only (from list above) and some other ones unless they are escaped by "\" or quoted by """ (so <some|[EMAIL PROTECTED]>, <some\,[EMAIL PROTECTED]> and <"some address"@domain> are valid adresses, whereas <[EMAIL PROTECTED]> is not valid address, because backslash escaped ">", so ">" is part of domain name, so address is not ending by required ">", however lmtp accepts this address as valid). And chars "?" and "|" are allowed by RFC. I understand "|" may be dangerous on recipient side (maybe interpreted as a process pipe), but on sender side? This (MAIL FROM) is used for Return-path header only, isn't it?
