It still isn't really clear to me why this is going on.
I am wondering what that sendmail process is doing.
As you can see, Dovecot waits for it to finish for 30 seconds
(override
with submission_timeout setting).
Can you try invoking sendmail manually from command line? Does it
work?
Is it hanging for more than 30s?
I think the real error here is the postdrop one (sendmail is a wrapper
around postdrop). It's a permission denied error which leads me to
believe it may be an selinux (or similar) issue. I wouldn't be
surprised if sendmail works from the command line but fails when
executed from sieve because selinux has it blocked for sieve.
If you're running selinux or apparmour or similar, check your logs for
that (audit log for selinux) and look for denials. You cna also try
setting selinux to permissive and trying the operation (setenforce 0).

Thanks for the responses. Running sendmail from the command line is
successful, which strikes me as odd. So it is only failing when sendmail
is invoked from sieve, but I don't yet understand why. I haven't made
any recent significant changes to the mail environment. I haven't
updated from postfix 3.2.4-2 since 12-16-17 when my distribution
released the packaged updated, but I didn't notice the issue at that
time until around 12-27 when I started getting emails about the reported
permission denied error and sendmail timeout.
