#49355 [NEW]: Unable to properly fold To/Subject in emails

From: php dot net at chris dot cs278 dot org Operating system: Various PHP version: 5.2.10 PHP Bug Type: Mail related Bug description: Unable to properly fold To/Subject in emails Description: ------------ The SKIP_LONG_HEADER_SEP macro only permits CR-LF-WSP as a separator which works fine for SMTP, but sendmail under NIX requires LF as the new line character. The macro doesn't skip over LF-WSP which causes the LF to be replaced with a space, unfolding the header. This makes it near impossible to use UTF-8/etc. encoded strings for these headers. I posted to internals about this problem: http://marc.info/?l=php-internals&m=125110373328523&w=2 Reproduce code: --------------- mail('tester@example.net', "Reproduction test e-mail for PHP bug breaking the correct wrapping\n of e-mails with long To/Subject headers.", 'Testing...'); Expected result: ---------------- To: tester@example.net Subject: Reproduction test e-mail for PHP bug breaking the correct wrapping of e-mails with long To/Subject headers.
