[TYPO3-english] problem with dmailsubscription

[horace grant]

hi,

i am using the dmailsubscription extension. i got everything to work like i
want except for one problem.

setting those lines:

plugin.feadmin.dmailsubscription.email = admin at domain.com
plugin.feadmin.dmailsubscription.emailName = admin

seems to cause some weird error. the "create saved" message doesn't show up
anymore (no page gets rendered at all) and no verification email gets sent.

without those two lines everything works fine but of course i would like to
display a proper sender adress in the mails.

what could be the reason for this?

cheers,
horace
