--- Comment #13 from Peter Schiffer pschiffe@redhat.com --- This package is intended only for EPEL6, because we need it as an alternative to the mailx package. Mailx package in RHEL-5 is based on this, bsd-mailx, but in RHEL-6 it's based on heirloom mailx, which is not 100% percent backwards compatible with bsd-mailx.
Also there might be a problem with OpenBSD sources, because so far I found only CVS urls for them and no http url, but I can try to look again...
