"the sendmail package version 8.12.6 contains an openssh like trojan. this issue is on the cert site at CA-2002-28 . is openbsd-current sendmail source infected with this trojan?"
OpenBSD shouldn't be affected by this as only every now and then the Sendmail sources are updated. However, some admins who used home rolled Sendmail installations may be affected. Note that the modified distfile was up and available for several days (unlike the OpenSSH Trojan, which was fixed in under a day).

    Note that the trojan is actually active only during the install phase. What this means is that the binary which is actually built is apparently not trojanised.

    You are vulnerable during the installation process when a process opens up a connection on the usual 6667/tcp.

    The OpenSSH trojan was available for multiple days.

    since this is the second time this has happened, and probably not the last time, do we have any kind of methods of preventing this, or elliminating this from happening? I am leaning more towards a program/daemon that activly monitors pgp/md5 keys X times a day, based on a list of last known signatures. When it finds one, it lets someone know. I don't know if this would be a good idea or not, but I was just thinking about this incident and the openssh incident, maybe the idea is good, maybe i should just STFU.

    You mean there's still people using sendmail? I think alone should be reason enough to switch to a much better MTA, such as exim or postfix. Personally I prefer to use postfix on smaller sites, and exim on larger sites. Postfix works excellently with OpenBSD, and of course it's in ports.
