    I have one customer who did set up a mailman list and subscribed people and suddenly I have hundreds of message in the mailqueue stuck with the following error message (host and domain names changed):

    I contacted support and guess what I got back? See the message below. This tech support person needs to ask me in an email if the ip has reverse DNS set up. This is hilarious. Do cpanel support people know how to use nslookup or dig?

    ------------------------------
    Hello,

    Just out of courisity, did your datacenter setup reverse DNS on the Mail Server IP?

    Thank you.

    Several people have had the same problem and there are all sorts of advice in the forum on what causes this. But it also seems that people have tried to change numerous settings with various results.
    This is an issue that needs to be looked at and a fix that works for all needs to be applied.
    I will keep everyone posted on the outcome with support!

    Yes, AOL and many others do require a PTR record but they do not require the PTR to be the same as the FQDN in the helo string.
    But this problem is different. AOL sends you a 545 or 550 error when they do not accept mail. The error message in this case says it is an unroutable mail domain.
    And the cpanel tech could have easily checked if there is a PRT record (yes, there is one and always has been).
    So I wonder how long it will figure out for them what the real issue is. I suspect some incompatabilites between mailman and exim......

    By any chance do you have the max number of emails a domain can send per hour set to something other than 0 (unlimited)?

    Getting yahoo.com unrouteable domain on a box that's been running fine for months. New cpanel updates may have caused issue?

    Please help. No changes to Exim conf or hosts file or anything yet getting bounced emails

    Thanks

    I had a similar instance happen to me like the aol.com and yahoo.com domains have been setup on the server and the server is attempting local delivery to that domain, but since abcde@aol.com does not have an address on the server, it fails.

    Wonder if you are facing the same...

    I upgraded to cpanel 9.3.0-c4 and whm 9.2.0 earlier this morning because of the exim update.

    PRIOR TO THE UPGRADE, EVERYTHING WAS WORKING FINE.

    NOTHING was changed at all prior or after and now when someone tries to send e-mails out using Neomail or Squirrelmail, etc (haven't tested an imap or pop client yet) it says that valid domains are "unroutable mail domain" from @yahoo.com or @aol.com.

    The prevent nobody user from sending e-mail box was never checked, but I checked it and saved it and unchecked it and saved it just in case, but that doesn't help either.

    Inbound wasn't working either until I unchecked the "verify sender" checkbox that got checked somehow.

    I'm at a bit of a loss here and it's frustrating because no one in the entire server of all the domains I host can send e-mail. Searches on this board and the internet doesn't give any solutions, just more frustrated people. Help! Please?

    BTW, this is running on a Redhat 7.3 box, and Exim says version 4.24.

    thanks,
    charlie

    Charlie,
    This sounds like a DNS problem to me. Also, why does Exim say 4.24 if the you just upgraded to the latest Exim which is 4.34?
    Did you check the /var/log/exim_rejectlog file to see why emails are rejected?
    Did you try a simple dns lookup on your machine for one of the domains? What are your /etc/resolv.conf settings?

    cyberspirit.. thanks for the response.

    i thought similar, but everything else works fine. and like i said nothing changed before or after. also, i shelled onto the server and tried pinging yahoo with success. websites still show up no problem, php scripts run, inbound mail now works, but only the outbound mail.

    i'm not sure why it's 4.24, that's what the non-delivery notice says. i upgraded to release last night and tried the current tree just a while ago and that still didn't solve the problem.

    do i need to a manual rpm update of exim? and won't that break cpanel?

    cyberspirit...

    thanks for pointing out the exim version.

    although i upgraded to release and then current and rebooted several times, it didn't help. but it did get rid of the red exim security alert in whm.

    i fixed the problem. after you mentioned the version, i went to shell and ran /scripts/exim4 and that updated exim to 4.34 and now e-mail works. thanks. hopefully this helps others who may have this problem.

    OK I am having the same problem.

    Try running exim -bt test@hotmail.com

    Post what results you are getting. Try an email address that is bouncing.
