Browsing through the source code to find some properties of deliver I stuck here: --- dovecot-1.2.rc3/src/lib-mail/message-header-parser.c.orig 2009-01-07 19:33:26.000000000 +0100 +++ dovecot-1.2.rc3/src/lib-mail/message-header-parser.c 2009-04-23 09:53:08.000000000 +0200 @@ -284,7 +284,7 @@ Exception to this is if the value consists only of LWSP, then skip only the one LWSP after ':'. */ for (pos = 0; pos < line->value_len; pos++) { - if (!IS_LWSP(line->value[0])) + if (!IS_LWSP(line->value[pos])) break; } I'm not clear if this was really indented but the for-loop does not use the variable pos in the loop body. The expression !IS_LWSP(line->value[0]) is invariant and always false if the first character after ':' is a white space, forcing the loop to go through the whole value. This happens only if flag MESSAGE_HEADER_PARSER_FLAG_SKIP_INITIAL_LWSP is active. I saw this in 1.1.4 too. Johann Klasek -- Johann E.
