Re: continuing email problems



Starting with the first error message (from your other message) :

  techbrl@chpi.org
      SMTP error from remote mailer after RCPT TO:<techbrl@chpi.org>:
      host smtp.mailtag.com [66.84.135.12]: 554 Undeliverable TO address:
      <techbrl@chpi.org>

Ok, so exim on your system tried talking to smtp.mailtag.com
(66.84.135.12).  Trying that I get this :

    $ telnet 66.84.135.12 smtp
    220 mailtag.com, Wildcat! ESMTP Server v5.6.450.3 ready
    helo foo
    250 mailtag.com
    mail from:<>
    250 <>... Sender ok.
    rcpt to:<techbrl@chpi.org>
    554 Undeliverable TO address: <techbrl@chpi.org>

The problem appears that the other system not accepting the
recipient's address.  Looking at the list of MX records for chpi.org I
see that that machine isn't supposed to be receiving mail for that
address.

The solution to this is to authenticate :-). 

I'm going to take a guess that smtp.mailtag.com is the server your ISP
provides for you to send mail out and you are trying to use it as a
"smarthost".  That's great, you just need to configure your side to
authenticate so that the server will accept recipients in different
domains.  Look at the last section of your exim.conf file.  It should
have a section (commented out) that looks like this :
    cram_md5:
       driver = cram_md5
       public_name = CRAM-MD5
       client_name = username
       client_secret = password
Uncomment it and change "username" and "password" to the username and
password your ISP gave you.

It probably is.  (particularly if you are using fetchmail to pull it
and have exim deliver locally)

It could have an effect.  If your ISP was using IP-based checks to
determine whether or not you could relay, and then your IP changed,
then maybe it fails those tests now.
