But my point wasn't this, I didn't even take into account that postfix is pretty much secure in this regard (e.g. no strange config directives). It was meant more generally, something that's always to be considered when _testing_ something: Not only make sure that it works, also make sure that you don't impose foreseeable risks. Since I made a general (i.e. daemon-independent) proposal for testing whether SMTP works, I thought this might be a needed addition. -hwh -- gentoo-user@gentoo.org mailing list
