I hope you know what you are doing coz commenting out "feature lines" (randomly) "just" to get sendmail "working" is not a good idea ... for example I would not comment out these: FEATURE(delay_checks,friend) FEATURE(`dnsbl',`zen.spamhaus.org',`go away spammer') FEATURE(`no_default_msa',`dnl')dnl FEATURE(`smrsh',`/usr/sbin/smrsh')dnl FEATURE(`virtusertable',`hash /etc/mail/virtusertable')dnl FEATURE(redirect)dnl FEATURE(always_add_domain) FEATURE(use_cw_file) FEATURE(use_ct_file) FEATURE(local_procmail,`',`procmail -t -Y -a $h -d $u')dnl FEATURE(`access_db',`hash -T<TMPF> /etc/mail/access.db')dnl FEATURE(`greet_pause',5000) FEATURE(blacklist_recipients) FEATURE(masquerade_envelope)dnl FEATURE(masquerade_entire_domain)dnl FEATURE(allmasquerade) But I comment out (and highly recommend that) these: dnl FEATURE(`accept_unresolvable_domains')dnl dnl FEATURE(`relay_based_on_MX')dnl So I assume the SMART_HOST is your ISP's mailserver? When you send an email "internally" what is the error in the sendmail maillog (as your mailserver becomes the recipient)?
