You hostname of the sendmail host does not resolv from external. If you have control over DNS, then having a FQDN can solve your problem. To use a smart host for relaying you will have to activate the preconfigured entries in /etc/mail/sendmail.mc. To be able to use SSL you will have to create a certificate. To let Sendmail authenticate as a client against the smart host you will have to add auth info data into the access map file, see: http://www.sendmail.org/~ca/email/sm-812.html#812AUTH Alexander -- Alexander Dalloz | Enger, Germany | GPG http://pgp.mit.edu 0xB366A773 legal statement: http://www.uni-x.org/legal.html Fedora Core 2 GNU/Linux on Athlon with kernel 2.6.10-1.14_FC2smp Serendipity 23:34:03 up 13 days, 10:42, load average: 0.55, 0.36, 0.36
