Self-explanatory, I hope (note the period on the end of the username);
sieve/pigeonhole does not allow you to have senders which end with a
period, which means that any UNIX users with such usernames who send
mail have it rejected by sieve:
# useradd testuser.
# su - testuser.
$ mail da...@example.com -s 'testing'
123
.
[testuser.@levi ~]$ logout
# less /var/log/maillog

envelope sender address 'testus...@myhost.example.com' is unparsable

Why would anyone have a UNIX username ending in a period? For one, web
hosting companies may use your domain name as your username - but be
subject to a 32-character limit, so your domain name gets truncated.
I would have expected to see that address escaped as
"testuser."@myhost.example.com. I notice that I haven't tested such
addresses much with Sieve and I don't actually know in what form MTAs
provide such addresses to the LDA. I'll give that a look soon.
