Looking at illumos.org/issues/16918 makes me wonder if the in-gate sendmail is still being used

→ BUG 16918: Port tls.c to OpenSSL 3.x API (New)

I know OpenIndiana and Tribblix ship upstream sendmail instead

Looking at OmniOS, it appears dma is preent by default, but users can switch to the in-gate (?) sendmail

I have never understood why do we keep it in gate [and do not update].

Yeah, hard to picture what needs to be maintained in illumos of sendmail to keep it working?

I imagine it's like SunSSH - there are a set of different behaviours that some people might have come to rely on

Are those behaviors that can be expressed in sendmail's conf vs having to have a full custom src though?

Well, that's annoying, upgraded the project antique IBM with an LSI 3008 HBA. Two 850 Pro's setup as a mirror, UEFI booting, all is well.
