Dear SL, ist there an easier way to configure sendmail than what I did? Something like system-config-sendmail or so? I need sendmail to omit the hostname from the envelope from address (i.e., it should be [log in to unmask] instead of [log in to unmask]). I also want it to use a smart host for delivery. What I did: I first installed sendmail-cf (in addition to sendmail), then edited /etc/mail/sendmail.mc (I activated the lines define(`SMART_HOST'..., MASQUERADE_AS(`..., and FEATURE(masquerade_envelope) ) and then ran make. I am not enough of a sendmail expert to know whether all that is correct. I would feel more comfortable if some higher-level configuration tool would offer me a preconfigured sendmail configuration for the situation "use a smarthost". This is Scientific Linux SL release 4.1 (Beryllium). -- Klaus Wacker [log in to unmask] Experimentelle Physik V http://www.physik.uni-dortmund.de/~wacker Universitaet Dortmund Tel.: +49 231 755 3587 D-44221 Dortmund Fax: +49 231 755 4547
