    Hi,
    Recently I have encountered a problem with Gmail accounts ; I can not send Any messages to gmail from our server by ip address 64.85.165.82 at all.
    Kindly refer me the best cure to fix the problem and I declare that any needed item will be available to present.
    Some of the messages appearing are listed below.
    Many thanks in advance.

    Our server ip's :
    64.85.165.82
    64.85.165.83

    Very truly yours,
    Hamed Niki

    your IP aren't blacklisted. to it seems like a network error as your server can't reach Gmail's servers. it can happen due to large no of reasons. few of them

    * Remote host down( highly unlikely)
    * network problem on your end.run a traceroute to 72.14.247.114 to debug.
    * Firewall blocking

    Restart exim and then check.

    BTW is it only gmail facing problem or other domains too?

    Check the O/P of the command "exim -bt h.cpuman@gmail.com".. It will show the correct router used by Exim to reach the remote SMTP server..

    If it is failing, check the router used and do check if gmail.com is listed in localdomain's list..

    Also check if you are able to connect to gmail's SMTP server:

    telnet 72.14.247.114 25

    Code:
    h.cpuman@gmail.com
      router = dk_lookuphost, transport = dk_remote_smtp
      host gmail-smtp-in.l.google.com      [209.85.210.65] MX=5
      host alt1.gmail-smtp-in.l.google.com [209.85.222.5]  MX=10

    Do you have anything running like PortSentry or use iptables to place restrictions on IP's/routes that could have gotten in there somehow?

    When all else fails and if you don't have time to troubleshoot:

    # /scripts/reseteximtodefaults

    Although it smells more of a DNS thing.

    Also, reverse lookups are working for your IP's, but you don't have any MX records which may be a part of the problem.

    Code:
    john@pdxor-db02~:$ dig alborznic.specialservers.net mx
    
    ; <<>> DiG 9.2.4 <<>> alborznic.specialservers.net mx
    ;; global options:  printcmd
    ;; Got answer:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 49856

    ;; QUESTION SECTION:
    ;alborznic.specialservers.net.  IN      MX
    Perhaps Google sees this lack of MX records as it relates to those two IP's?

    The config for specialservers.net seems to be correct:

    Code:
    john@pdxor-db02~:$ dig specialservers.net any
    
    ; <<>> DiG 9.2.4 <<>> specialservers.net any
    ;; global options:  printcmd

    Yes, the "any" function works as well, but notice you still have no MX records.

    n3twork.net.            14224   IN      A       XXX.XXX.XXX.XXX
    It's just a guess, simply because I used "any" and "mx" when I repetatively queried the domain and no responses were returned.



    Anyone else have suggestions?

    Okay, I looked at the reverse entries for the two IP's in your first post.

    Reverse lookup reveals PTR = alborznic.specialservers.net. for both IP's.

    dig -x 64.85.165.82

    ; <<>> DiG 9.3.4-P1 <<>> -x 64.85.165.82

    ;; QUESTION SECTION:

    ;; ANSWER SECTION:

    ------------------------------------------------------------------

    Using 'dig alborznic.com mx" I found that the MX record is simply "alborznic.com" - this is where I became confused because 'dig -x 64.85.165.82' doesn't return a hostname that matches your MX record.


    Would anyone care to constructivly criticize or support my assumption that this is a reverse dns thing? I imagine if you had your server provider change the PTR records to alborznic.com for your two IPs, that it could correct the issue.

    I believe the MX record and RDNS must match to avoid trouble.

    Note the bold text - shouldn't this read h.cpuman.gmail.com instead? I've also not seen a question mark in an SPF record before.Something else to correct while you're at it.

    You will also need to place quotes before & after the SPF record, if I'm not mistaken.

    - I'm pulling this from http://network-tools.com/default.asp...=alborznic.com by the way.

    Any number of these issues could be causing the problem.

    Let me correct myself. As long as you've quoted the first and last line of the SPF in your DNS zone, then you're OK.

    It's hard to tell who Google does and doesn't use as authoritative spam sources. No one here can give you that answer. However if you're listed, you should first ensure your server isn't spamming without you knowing it and then ask to be delisted from that spam list.

    Generate exim stats using the 'eximstats' command to find the top users sending mail from your server.

    If you are sure that your servers (both 64.85.165.82 and 64.85.165.83) aren't spam sources then take steps to delist the IPs.

    As a temporary measure, you can even try changing the interface IP of Exim.

    you main problem is in network.

    If you can't telnet to google mail server IP's then how you want it to send mails.
    Ask your hosting company about this. Say them that you can't telnet to google mail servers IP's on port 25.

    Maybe they blocked google IP's to port 25.


    Successful telnet example:

    root@server6309:# telnet 72.14.247.114 25
    Trying 72.14.247.114...
    Connected to 72.14.247.114.
    Escape character is '^]'.
    220 mx.google.com ESMTP 30si9890714agc.69
