mail-mta/opensmtpd-6.0.2_p1 was apparently deleted because of bug #683284. mail-mta/opensmtpd-6.0.3_p1-r1 is unstable and may have bug #670632. mail-mta/opensmtpd-6.4.0_p1 isn't even unstable, probably due to being LibreSSL-only. Can we either get: 1. mail-mta/opensmtpd-6.0.2_p1-r1 with virtual/pam dependency removed, or 2. mail-mta/opensmtpd-6.0.3_p1-r1 stabilized? I'm not sure "unmask the unstable one" is the right choice, but I will if I must.
Open a stabilization request for opensmtpd-6.7.1_p1.
