You're really asking for trouble letting the qmail maintainer enable every possible qmail patches by default! on AMD64, gentoo's qmail qmail-remote keeps crashes while it works fine on x86. ... and vanilla qmail install works fine on amd64 without all your ugly patches and add-ons! qmail-maildir++.patch is using the printf family and violates the coding standard used in qmail. All qmail patches shouldn't be enabled by default! People trust qmail for its robustess but the portage version is really floppy.

Not sure why this was assigned to security, reassigning to maintainer
Here is another example of a useless patch: # Apply patch for local timestamps. # This will make the emails headers be written in localtime rather than GMT # If you really want, uncomment it yourself, as mail really should be in GMT epatch ${DISTDIR}/qmail-date-localtime.patch.txt Why is this enabled by default???
Now this is probably the culprit patch which causes all the crashes: # this patch merges a few others already EPATCH_SINGLE_MSG="Adding SMTP AUTH (2 way), Qregex and STARTTLS support" \ EPATCH_OPTS="${EPATCH_OPTS} -F 3" \ epatch ${DISTDIR}/qregex-starttls-2way-auth-20050523.patch Maybe the maintainer should have added these words of warning (from the patch's author) as a comment in the ebuild: A word of warning: the TLS part of this patch is not type-safe at at least one point (hey, I didn't write it.) I don't think this causes problems on i386 architectures, but it made qmail-smtpd crash frequently on an Alpha. Commenting out the substdio_fdbuf(...); call in qmail-smtpd appears to fix the issue.
Ok this ebuild is an abomination! You can't disable any patches because of cross-dependencies. Can we have a vanilla qmail ebuild and move this qmail port to qmail-bloated please.
if you want to reproduce the crashes, try on a amd64 box and email someone at gmail.com, it will crash everytime. In the meantime, this will temporarely fix the problem at the expense of TLS support. echo mail-mta/qmail -ssl >>/etc/portage/package.use emerge qmail I guess I'm switching to postfix really soon.
This bug also has me in a jam; I previously had an x86 server that I migrated (without choice) to an amd64. Previously I had been offering TLS support, which is unfortunately causes crashes in the amd64.
Due to the use of a newer version of the TLS patch, the qmail-1.03-r16 ebuild fixes the segmentation fault related to the SSL use flag in qmail-remote. Please closet this bug.
Thanks. Please note that it's worth trying the ~-ebuild if the stable one doesn't work in almost all cases.
How well has this new patch been audited? I see a lot of useless patches in this qmail ebuild. Patches that don't even respect djb coding standard and which introduce new bugs. Don't cry when your machine gets hacked because of this crappy ebuild and careless maintainer.
