Could someone tell me what is incorrect in my .hgrc configuration? I am trying to use gmail to send a e-mail after each push and/or commit.

.hgrc

[paths]
default = ssh://www.domain.com/repo/hg

[ui]
username = intern <[email protected]>
ssh="C:\Program Files (x86)\Mercurial\plink.exe" -ssh -i "C:\Program Files (x86)\Mercurial\key.pub"

[extensions]
hgext.notify = 

[hooks]
changegroup.notify = python:hgext.notify.hook
incoming.notify = python:hgext.notify.hook

[email]
from = [email protected]

[smtp]
host = smtp.gmail.com
username = [email protected]
password = sure
port = 587
tls = true

[web]
baseurl = http://dev/...

[notify]
sources = serve push pull bundle
test = False
config = /path/to/subscription/file
template = \ndetails:   {baseurl}{webroot}/rev/{node|short}\nchangeset: {rev}:{node|short}\nuser:      {author}\ndate:      {date|date}\ndescription:\n{desc}\n
maxdiff = 300
