search for: accept_unresolvable_domains

I have centos 4.8 i686. It has stock sendmail. see file below. I am getting reports that it is an open relay. I have searched all around and it seems like it should be closed. I have dnl for accept_unresolvable_domains. What can I do to close my sendmail. Thanks, Jerry My sendmail.mc is as follows: --------------------------------- divert(-1)dnl dnl # dnl # This is the sendmail macro config file for m4.

Domain of sender address root at localhost.localdomain does not exist What else do i need to edit as there is something that talks about sending from unresolvable domains but this is already allowed i think FEATURE(`accept_unresolvable_domains')dnl any ideas ? thanks

I have a problem getting spamd and sendmail (both stock CentOS4 rpms) to work together on a couple of smtp relay machines. This is clearly a configuration issue and no doubt revolves around my lack of comprehension of how this is to work. Basically, the setup consists of two frontend public smtp transports that redirect all email through a firewall to an internal imap server for final

I know this is a "generic" question, but fully CentOS related. I attempted to set up i386 v.4.1 on my primary computer at the co-located site, and thought I had everything squared away till I discovered the machine was refusing mail connections. AFIK, I had no firewall or other objects blocking port 25. It has been my experience that with most arch's and versions where sendmail is

Hi - OK not really an Asterisk question but it is affecting one of my favorite features - emailing voice mail! I've posted on some Linux forums and sendmail.org but no response so I'm hoping someone will take pity on me ;-) My ISP requires SMTP authorization and I'm having a heck of a time getting it to work. I've included the following below: Asterisk 1.4.21 CentOS 5 Sendmail
