Please have a read of my article, make sure your Reverse DNS record is configured correctly, that your FQDN on your SMTP Virtual Server is correct and that you are not blacklisted:

Would you like to post your domain name and IP address (which I will hide for you), then I can check for you?

You indeed look fine and RFC compliant.

Can you send me a test email to alan @ it-eye.co.uk please and I'll see if my anti-spam software gets upset with you.

Alan HardistyCo-OwnerCommented:
Good - email received which would indicate my server doesn't dislike you.  I'll have a look at my server in a while and will check that all looks good, but at the moment, the problem is looking like a problem at the receiving end, not your end.

How long has the been occuring? Have you went through a ISP change recently? Do you hold your MX record or is that kept somewhere else ( I have a 3rd party that scrubs my e-mail before my we recieve). Screenshots looks like everything is in order but the MX record sounds to be messy. Can you sensd mail internally?

Server logs look fine my end - you don't have any problems that I can see.

Please contact the recipients and ask them why they are blocking you.

Do you use Autosignatures in ALL your emails?  Can you send a test email without one to a problem recipient.  Does it get there?

I have contacted them and their IT swears its on my side. After I had them check it she suddenly started recieving emails. I ran wireshark and have the logs if it would help you. I tracked the message she recieved yesterday against the ones she wasnt getting. They all ended the same way transfered to mx.google.com. The logs show it getting  there but where it goes after that beats me. Now again today she says she's not recieving my test emails.

Any clue? Yes we changed ISP's recently but i went back to long before the switch to prove to myself it was or wasnt the fault of the ISP. Same out come transfered to mx.ggole.com/

Funny that - I don't see any problems your side and you talk to them and then suddenly the emails arrive!  Smells of a problem their side that they either don't understand or haven't got the skills to resolve.

Can you please send them an email and CC me in on it so that I can see their domain name / details so that I can check their side as much as possible?

Ugh!  They use Google - that's going to be fun to try and resolve!

Have you tried to use telnet to manually send an email to them to see if you get any random responses?

shawkins331Author Commented:
no havent used it alot so not quiet sure how to do it.

Alan HardistyCo-OwnerCommented:
Okay - from a command prompt type the following:

telnet aspmx.l.google.com 25
ehlo mail.yourdomain.com
(wait for their response)
mail from: <you@yourdomain.com>
(wait for their response)
rcpt to: <them@theirdomain.com>
(wait for their response)
Data
(wait for their response)
Subject: Test Message Via Telnet
Hello - please reply if you receive this message

.

Quit

Do you get all the way to the end without error?

Do they receive the test email?

Also as an added note when I changeed ISP services, I had to change my DNS entries on my firewall and also have my new ISP check Rdns entry. Another e-mail prvider that relies heavily on Rdns is AOL, so if you know anybody with an AOL account try to e-mail them and see if the e-mail goes through if not then you have found the answer.

I just reread the part about auto signitures.. yes we have to use them its company policy.

Alan HardistyCo-OwnerCommented:
Did you put a blank line after the "Hello - please reply part" and then a full-stop and another return?

That closes the message.

shawkins331Author Commented:
No I stoped at the 'Hello Part...i put it in and hit enter and it was waiting  then just timed out.

Alan HardistyCo-OwnerCommented:
Please try again - it was waiting for you to press enter then add a full-stop and then enter again.

Was this what you were looking for?

Alan HardistyCo-OwnerCommented:
Yep - that the submission to their server.

They should then receive the email and then have a chance to reply to it.

shawkins331Author Commented:
ok kool...so now i play the waiting game. At least i know it hit their server right.

Alan HardistyCo-OwnerCommented:
Yep on both counts!

Mind you - a manual test can produce different results - but it might help : )

shawkins331Author Commented:
so you think they are blocking us for some reason. I guess I go back to them and see if they can see why they may be blocking us. or is it google that is doing it.
0
 
Alan HardistyCo-OwnerCommented:
Could be Google.  At least you know you can manually send to them - so what happens after that is anyone's guess.

Can you call to see if the test message arrived?

Finally heard back and she has not recieved any emails including the telnet message. Now where do i go?
0
 
Alan HardistyCo-OwnerCommented:
Tell her Google are filtering her messages and that she needs to sort it out from her end.
0
 
shawkins331Author Commented:
Thanks will do and i will post back by monday. You help me feel better it wasnt on my end. And thanks for teaching me that telnet trick. Question though...if i was in her server wouldnt i have bypassed google?
0
 
Alan HardistyCo-OwnerCommented:
Her server is Google - so all filtering is done on Google, so she needs to work out why Google doesn't like you and resolve it as your config is fine from everything I have checked.

Would love to hear the outcome!

Yep so far I was right! Good Luck on the rest of your troubleshooting.

shawkins331Author Commented:
Right about what? I had already checked every thing you were talking about and Alan double checked it to make sure i was correct. We proved its not on my end and since i went back and verified by tracking messages long before the ISP change over against what i was seening now that it was not the ISP change over that caused anything.
