Package: alpine Version: 2.20+dfsg1-7 Severity: wishlist Tags: patch I’ve got eMail contact with a person using a big Telco’s webmailer which apparently chokes ok “CHARSET=UTF-8” but handles “charset=UTF-8” just fine.
Please find attached a patch working around this recipient side bug by sending what it eats. (I’m also reporting to that Telco, but you can imagine how well that is likely to go.) -- System Information: Debian Release: 9.0 APT prefers unreleased APT policy: (500, 'unreleased'), (500, 'buildd-unstable'), (500, 'unstable') Architecture: x32 (x86_64) Foreign Architectures: i386, amd64 Kernel: Linux 4.9.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=C, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/lksh Init: sysvinit (via /sbin/init) Versions of packages alpine depends on: ii libc6 2.24-9 ii libgssapi-krb5-2 1.15-1 ii libkrb5-3 1.15-1 ii libldap-2.4-2 2.4.44+dfsg-3 ii libpam0g 1.1.8-3.5 ii libssl1.0.2 1.0.2k-1 ii libtinfo5 6.0+20161126-1 ii mlock 8:2007f~dfsg-5 Versions of packages alpine recommends: pn alpine-doc <none> Versions of packages alpine suggests: ii aspell 0.60.7~20110707-3+b1 ii postfix [mail-transport-agent] 3.1.4-4 -- no debconf information
