You probably have in the stunnel.conf something similar to:

    [pop3s]
    accept=995
    {...}

    [comcast-pop3]
    accept=127.0.0.1:995
    {...}

accept=995 == 0.0.0.0:995 == (all localhost IPv4 addresses):995

Which includes 127.0.0.1:995

When the [comcast-pop3] service tries to bind to port 995
it fails because it is already bound at the [pop3s] service.
