Ah, I didn't know that. The docs state

"A Sieve filter contains instructions in the Sieve format that is
defined by RFC 3028. As this is a standard format, Sieve filter files
may already be familiar to some users. Sieve files should also be
portable between different environments. However, the Exim filtering
facility contains more features [...]"

and

"However, for Sieve filters, only issues that relate to the Exim
implementation are discussed, since Sieve itself is described elsewhere."

which made me think that Exim would support addflag; Now that I look
better I see that RFC 3028 doesn't mention addflag.

One more reason to use dovecot deliver for Sieve filtering :)
