Title: 550-Verification failed
Post by: Smitro on April 29, 2005, 03:58:09 PM
Hi,

My mail server is working great. Except for when I try to send to a particular server, then I get bounced back with this error.

Code: [Select]

<email@thisaddress.com>: host thisaddress.com[xx.xx.xx.xx] said:
    550-Verification failed for <myemail@myserver.com> 550-unrouteable mail domain
    "myserver.com" 550 Sender verify failed (in reply to RCPT TO command)


Yes, I replaced the addresses in it with fake ones. :-)

The weird thing is, I can send to this address using my sever if I use another email address (from another domain (eg. the email address my ISP's supplied me with).

My guess is that this is a reverse look up problem but how do I go about fixing it?

Yes. I'm running Spam Assasin on my server, and my guess is that the server I'm trying to send to does.

Ok, next question

Are you trying to use your ISP email address to send though your SME server ???

Cause if you are, you need to add your ISP email address to the white list of your SME server to be able to send emails though it

It works when I do, but when I use my own domain it fails.

Are you using a dynamic ip number or static ???

Do you have a registed domain name ???

Static and Registerd. I'm using DNS hosting to point the domain to my Static IP.

Ah ok, if you have done this all not long ago ((eg) today), you will have to wait a little for the SPF records to update with your domain and IP addy so you not seen as a possible spammer.

But at the same hand you might have another problem there too.

No, I put it all in place a couple of weeks ago.

I can send to hotmail and many others, infact, this is the only host that is giving me trouble. (it's a friend of mine's domain name, but he's getting it hosted overseas with some hosting company).

I would say it's them that's at fault, but I can send using any other domain names except my own. (I have 3).

Let me ponder on it for abit, and i will get back to you soon.

But i think you maybe right there is a problem with hosting somewhere.

I just did a google, seems I'm not the only one having this problem, but I can't seem to find an answer that I can understand.

Well, that doesn't help us to help you. Remote site is saying they don't like your sender email address. Whatever you have instead of myserver.com is what they don't like.

That's not weird. Give 'em a good sender address and they'll take your mail. Give 'em a bad one and they reject it.

Solution - use a good sender address, i.e. one that can be replied to.

I did.

I replaced real addresses with fake ones when posting to this forum.

It seems, from what I have been reading, when you send an email to this particular mail server, it recieves the email and then checks back with my mail server to see if there is an account on it that goes by that name. The thing is, there is an account on my mail server with that address. but it must fail when requesting the info back from my server. I have tried it from a couple of different accounts on my server.

Finally, found and fixed the problem. I had the MX record pointing at my IP address, all I had to do was to point it at my host name (mail.myplace) and it works no problems now.
