Re: AW: [suse-security] sendmail, avoiding open relay

Hello Carsten, you can prohibit sending mail of roaming user by pop-before-smtp

Smtp has no authentication mechanism, but pop has. after configured pop-before-smtp with sendmail only users with authenticated by pop first are allowed to send email through your mailserver. Jens

I tried to set up sendmail-sasl first, but had problems (better-sendmail had) to dlopen a library which was nevertheless there. So i don´t know if pop-before-smtp would work. thX & cu Carsten
