I am at my wits end with this... help please! FreeBSD 6.1-RELEASE Sendmail 8.13.6 (base)
I'm trying to accomplish what should be simple: 1) all outgoing From: email addresses should be stamped @ourdomain.com and not @server.corpdomain.com 2) All emails should be routed through the corp SMTP server (runs MS Exchange 5.5.2658.3). Users use Outlook clients to connect to the corp Exchange system and this SMTP server is our only gateway into it. I'm a bit rusty on my Sendmail and .mc stuff (I really haven't done much with managing email flow, sendmail or other MTAs) so I tried to brush up online as best I can, but I don't remember it being this hard in the past. At this point, here are the things I've put in my .mc file (I'm sure at least some is redundant or not needed/applicable, but this is the result of trying more and more ideas): define(`SMART_HOST', `internal.corp.smtp') define(`LOCAL_RELAY', `internal.corp.smtp') FEATURE(masquerade_envelope) FEATURE(always_add_domain) FEATURE(`masquerade_entire_domain') FEATURE(`allmasquerade') MAILER(local) MAILER(smtp) MASQUERADE_AS(`ourdomain.com.') MASQUERADE_DOMAIN(`outdomain.com.') (and did the required "make install" in /etc/mail to apply it) resolv.conf has the corp DNS servers in it. I can use ping and host on internal.corp.smtp and it resolves to the proper IP address. I also tried putting them into /etc/hosts along with entries for the versions of the name with the ending dot. 10.xxx.xxx.xxx internal.corp.smtp internal 10.xxx.xxx.xxx internal.corp.smtp. 10.xxx.xxx.xxx internal. I've even done up mailertable (plus the hash) with the following line: .ourdomain.com smtp:internal.corp.smtp This was the result of some stuff I read on the web regarding the error. Anyways, here is the problem that persists after all that: Sep 14 15:25:04 bugzilla sm-mta: k8EJOhhB067917: to=<[EMAIL PROTECTED]>, delay=00:00:21, xdelay=00:00:20, mailer=relay, pri=30985, relay=internal.corp.smtp., dsn=4.0.0, stat=Deferred: Name server: internal.corp.smtp.: host name lookup failure First of all, not sure why it's adding the trailing dot, but hence my additions to the /etc/hosts file. Secondly: how can it not resolve? bugzilla# host internal.corp.smtp internal.corp.smtp has address 10.xxx.xxx.xxx bugzilla# host internal.corp.smtp. internal.corp.smtp has address 10.xxx.xxx.xxx my /etc/nsswitch.conf file: group: compat group_compat: nis hosts: files dns networks: files passwd: compat passwd_compat: nis shells: files And not that it applies here... but I can telnet to the SMTP server on port 25, type out a session manually and send an email that way. So ultimately it can work. I just don't get this quirky name-resolution problem. I searched on Google and came up with tons of stuff on this, lots of people asking about it but not a lot of answers... I've tried the ones I've found, but a lot of discussions fell dead without the problem being solved. I'm hoping a fellow FreeBSD user (who knows more than me) might help guide me to a solution. Any ideas? _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
