After installing a newly available build of Solaris 10, sendmail was disallowing connections from anything but localhost. We tried taking a diff between sendmail.cf of older build and the new sendmail.cf and found that the old sendmail.cf had extra lines for DaemonPortOptions :
O DaemonPortOptions=Name=MTA-v4, Family=inet
O DaemonPortOptions=Name=MTA-v6, Family=inet6
O DaemonPortOptions=Port=587, Name=MSA, M=E
After including the DaemonPortOptions of MTA-v4 and MTA-v6, it started giving this error message:
opendaemonsocket: daemon MTA-v6: server SMTP socket wedged
So we removed the MTA-v6 line, and the above error stopped coming. Meanwhile I had googled this error and found this post on OpenSolaris forms. Based on the information, I reasoned that changing the parameter to false would allow connections from other hosts:
svccfg -s sendmail setprop config/local_only=false
svcadm refresh sendmail
svcadm restart sendmail
This worked perfectly fine. Since we don't use Solaris Zones, there was no need to use the pfexec command.

Hi,
Have you used both the ports i.e. MTA-v4 and MTA-v6, after changing the parameter to false?
Could you please tell the steps to follow if we are getting this error on Solaris Zones.
Thank you for this post. Commenting out the MTA-v6 entry allowed the client to start normally.
The config setting was already set to false, so I didn't need to make that change.
I can't say if both changes needed to be made, but disabling the MTA-v6 setting definitely helped.
