    Same Exim problem

    Don't have an answer to your problem, but if it makes you feel any better the same problem started for me after Exim has been running for months without a problem. Same error "host lookup did not complete"

    So does anyone have a solution to the problem of email building in the queue when it shouldn't be? Never had email keep piling up in queue because of the error mentioned above until we upgraded to CP6 if that means something.

    The domain name isn't in /etc/localdomains if you get this error - run /scripts/mailperm to fix that in a hurry. Then just wait for about 24 hours, and those messages should get delivered next attempt.

    I have a somewhat similat problem.... after upgrading to 6.0 my email service (incoming only)... seems to build up a mail queue of over 10,000 emails per night. I don't understand why and have yet to find a solution. The email is only going to pop accounts on the 1 domain on the server..... and it is not overloaded by a long shot. average MB per day is 5000 until I run a cleaner at night them it is back down to around 1000MB... any ideas?

    I'm interested in an answer/solution to this problem as well. Hundreds, even thousands, have been placed in the mail queue the past few weeks - is it related to the upgrade to WHM 6.0?

    I have yet to find a "real solution" and I am guessing nobody has either. Just like the rest of you...... I didn't have this problem until we upgraded to 6.0. Perhaps this wasn't tested with "heavy" mail usage. We have tweaked our exim and upgraded it to a newer version..... but the overall performance is still lacking.

    We are having a related mail problem.. It seems that exim can not find domains.. ( example: aol.com, yahoo.com, pacbell.com, hotmail.com, etc..) and the mail fails..

    Is there anything that can be done to fix this?

    Example failure message returned:
    this has recenty started after our latest upgrade to WHM 6.0.0 / Cpanel 6.0.0-S109
    HELP!!!

    Good Luck Steve.
    I am just waiting on someone..... or CPanel..... to come up with a solution....... This is the absolute worst I have ever been through and I have to constantly watch my servers mail queue now.... Cpanel needs to get on the ball..... or exim.. or both. As a member of many safelists..... and a host for safelists.... I can tell you that this is creating bounce problems everywhere.
    Including..... the connect issues you are having.
    SOMEBODY THROW US A ROPE...... LOL..... if nothing else to at least hang ourselves with and get the mail suffering over with.

    Yeah, it is fustrating. I've checked out as much as I can, with no solution to this problem..

    I hope there is a solution very soon as this is affecting my ability to service my accounts. (and it just plain looks bad!)

    Have you checked /etc/resolv.conf to see if maybe you've got bad NS entries there?

    What happens if you log into ssh and do a lookup on one of the domains?

    i.e.:

    dig unroutabledomain.com

    or

    dig -t MX unroutabledomain.com

    We have done just about everything..... and have double checked everything. This only started when the 6.0 upgrade was done. Also...... the email is coming in ONLY....... it is not being sent out. It comes to the server and goes to a pop account..... there is no reason for it to hold in a queue.
    As for the safelist servers they all have a problem. It seems some moments are just better than others. As for my hosting servers..... none of them have this problem..... however they don't have heavy mail usage. I will look into the options you listed...... and pray there is some hope..... but from everything I have read in here it seems to be more of a cpanel/exim problem than anything else.

    running dig works fine and the domain can (and are) resolved correctly.. Yet exim still won't send mail to them.. I receive a unroutable domain error.

    Exim has a spam security feature to keep mail from unroutable domains (i.e. if someone puts the FROM address in as me@notarealdomain.com) from reaching your users.

    It's actually a nice feature, as long as your server is routing DNS properly and can find the domains.

    That's the purpose of the dig command I pasted, to make sure that your server can route to the domain(s) in question. If you're getting the error on multiple domains, chances are very good that the nameservers in resolv.conf are either not active, incorrect, or nonexistant.

    [edit] This was posted as you were posting your results, so I'll post back in just a sec.

    I haven't experienced this problem myself, and I'm unfortunately at a loss if you are routing to the domain correctly.

    I hope someone else can help you more than I was able.

    Okay, let's try this.

    Open /etc/exim.conf
    Find the ROUTERS section. Your first router should start like this:

    lookuphost:
    driver = lookuphost
    transport = remote_smtp


    Does it? If so, you could try changing 'lookuphost' to 'dnslookup' and restarting Exim ... but be ready to change it back if that doesn't work.

    [edit] The dnslookup may be the configuration for Exim 4 and lookuphost looks to do the same thing for Exim 3 - but I'm not entirely certain.

    I am about to try this....... but could you just perhaps shed a hair of insight as to what this will accomplish? I do appreciate your hangin' round and posting BTW. :)
    Oh yeah..... the only reason I asked is because I am looking to try it on one of the servers..... however one is outgoing and one is incoming. So it may make a bigger difference on the outgoing I would think.
