Add support for the Binary Content extension [RFC3516].
Unfortunately as of Debian Wheezy it doesn't work for Dovecot with COMPRESS=DEFLATE [RFC4978] and non-synchronizing literals. perl -e 'use Compress::Raw::Zlib; print "a COMPRESS DEFLATE\r\n"; sleep 1; my $d = new Compress::Raw::Zlib::Deflate( -WindowBits => -15 ); $d->deflate("b APPEND TRASH ~{1+}\r\nx\r\n", my $buf); print $buf; $d->flush($buf, Z_SYNC_FLUSH); print $buf; sleep 1; ' | /usr/lib/dovecot/imap imap(guilhem): Panic: stream doesn't support seeking backwards Interestingly, it works just fine for non-binary literals: perl -e 'use Compress::Raw::Zlib; print "a COMPRESS DEFLATE\r\n"; sleep 1; my $d = new Compress::Raw::Zlib::Deflate( -WindowBits => -15 ); $d->deflate("b APPEND TRASH {1+}\r\nx\r\n", my $buf); print $buf; $d->flush($buf, Z_SYNC_FLUSH); print $buf; sleep 1; ' | /usr/lib/dovecot/imap However I can't reproduce the problem Dovecot 2.2.18 and Debian Sid (but it doesn't help to install Dovecot from testing to my Wheezy box.)
