I have a server with WHM and Cpanel in OVH Canada with a main ip +4 additional ipv4, 2 of which are assigned to their corresponding domain and 2 are unused: suppose the ips are:

144.217.55.5 (main)

167.114.80.108 (empty)
167.114.80.109 (domain1.com)
167.114.80.110 (domain2.com)   <-----
167.114.80.111 (empty)

When I use PHP to send emails, I connect via SMTP with the following conf

host: mail.domain2.com   <----
port: 465
encryption: SSL
username: xxxxxx
pass: xxxxxx

The problem comes when I see the exim logs:

2020-09-04 11:09:26 1kECP8-0002Ze-4L <= admin@dominio2.com H=(www.dominio2.com) [167.114.80.109]:43018 P=esmtpsa X=TLS1:ECDHE-RSA-AES128-SHA:128 CV=no A=dovecot_login:info@dominio2.com S=130398 id=d6243cac0e818469706920622447795b@www.dominio2.com T="Example email" for example@hotmail.com

As you can see in the log, "domain2.com" does not resolve to the correct IP (.110) but ... but to a wrong one (.109), This ends in a header received in outlook like this:

-----------------------------------
/END Recibed E-Mail in Outlook (Headers)
-----------------------------------

I configured exim via WHM and I am handling the / etc / mailsips and / etc / mailhelo files manually:

/etc/mailip

*: 144.217.55.5
update.dominio1.com: 167.114.80.109
web.dominio1.com: 167.114.80.109
dominio1.com: 167.114.80.109
dev.dominio2.com: 167.114.80.110
dominio2.com: 167.114.80.110          <------

/etc/mailhelo

*: server.myprimaryserver.com
dominio1.com: dominio1.com
web.dominio1.com: dominio1.com
update.dominio1.com: dominio1.com.ar
dominio2.com: dominio2.com             <-----
dev.dominio2.com: dominio2.com

So ... I don't understand why exim resolves the address mail.domain2.com to ip .109 instead of .110 ...

I was studying a little exim configuration options ... and I found this:

For messages from other hosts, the H and U fields identify the remote host and record the RFC 1413 identity of the user that sent the message, if one was received. The number given in square brackets is the IP address of the sending host. If there is a single, unparenthesized host name in the H field, as above, it has been verified to correspond to the IP address (see the host_lookup option). If the name is in parentheses, it was the name quoted by the remote host in the SMTP HELO or EHLO command, and has not been verified. If verification yields a different name to that given for HELO or EHLO, the verified name appears first, followed by the HELO or EHLO name in parentheses.

Misconfigured hosts (and mail forgers) sometimes put an IP address, with or without brackets, in the HELO or EHLO command, leading to entries in the log containing text like these examples:

H=(10.21.32.43) [192.168.8.34] H=([10.21.32.43]) [192.168.8.34] This can be confusing. Only the final address in square brackets can be relied on.

For locally generated messages (that is, messages not received over TCP/IP), the H field is omitted, and the U field contains the login name of the caller of Exim.

For all messages, the P field specifies the protocol used to receive the message. This is the value that is stored in $received_protocol. In the case of incoming SMTP messages, the value indicates whether or not any SMTP extensions (ESMTP), encryption, or authentication were used. If the SMTP session was encrypted, there is an additional X field that records the cipher suite that was used.

The protocol is set to “esmtpsa” or “esmtpa” for messages received from hosts that have authenticated themselves using the SMTP AUTH command. The first value is used when the SMTP connection was encrypted (“secure”). In this case there is an additional item A= followed by the name of the authenticator that was used. If an authenticated identification was set up by the authenticator’s server_set_id option, this is logged too, separated by a colon from the authenticator name.

The id field records the existing message id, if present. The size of the received message is given by the S field. When the message is delivered, headers may be removed or added, so that the size of delivered copies of the message may not correspond with this value (and indeed may be different to each other).

The log_selector option can be used to request the logging of additional data when a message is received. See section 53.15 below.

PS: If you want to know any other configuration in particular, just ask and I will send you more info.

Edit 1:

At the request of Anonymous I edit the question to add the DNS resolution using the nslookup and dig commands. Add the dig command results from my server where I have the problem with exim, and try to query another dns server (8.8.8.8) to be able to compare, I also add the Reverse DNS resolution. I am changing the ips, if they do tests it will not give them the same results, it is a matter of privacy, if someone wants to commit to investigate more, they could send the real data by private message.

  • Are you sure that the problem lies with Exim ? I would check the DNS configuration for your domains, check if you have PTR records set up for your IP addresses, review the IP addresses in your DNS configuration and also try to resolve the domain names from the server where Exim runs. Use dig or nslookup from the command line for example. Also verify you don't have stale entries in your hosts file. – Kate Sep 05 '20 at 21:28
  • We don't handle questions about cPanel systems here. You should seek help from cPanel support. – Michael Hampton Sep 08 '20 at 12:57
  • Hi Anonimous, no ... I'm not sure it's exim who is "lying". Add the information you request, under the section "edit 1". **I would suspect that there is some kind of configuration error in how exim results the "IP" to which the "HOST" belongs (mail.domain2.com) and for some reason as you decide, take it wrong.** As soon as I can I will review the virtualhost files in detail. Thank you! – Leonardo Jauregui Sep 08 '20 at 13:41
  • Sorry @Michael Hampton, I didn't know, do what you have to do, delete it, close it, etc. I'm going to post to the cpanel forum, to see if they really want to help out there! PS: Thanks Anonimous! You do take a risk by collaborating and I appreciate it! xD – Leonardo Jauregui Sep 08 '20 at 13:52
  • Have you checked the PTR for 167.114.80.109 eg: `dig -x 167.114.80.109` – Kate Sep 08 '20 at 20:13
  • Hi @Anonymous, yes and I add the result of dig -x to ip .109 as "edit 2:" in the post, but I don't see anything strange. any other idea? – Leonardo Jauregui Sep 10 '20 at 12:44
