It seems that this bugfix resolves the sendmail issue but causes a TCP reset if the TCP connection is on the FD 0:
local *STDIN = IO::Handle->new_from_fd( 0, "r" ); This is described in Debian bug #674924. It can be reproduced by sending a ticket reply via web. Mail gets set but the HTTP POST connection is reset. It looks like the above fix has some unexpected side effects. Reverting the following file from 3.8.8-7+squeeze1 makes both problems disappear: /usr/share/request-tracker3.8/lib/RT/Interface/Email.pm -- Valentin -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
