On a raq 3 located at TB, i have a lot of problems receiving emails.
This is the error you get when sending a message to these accounts:


----- The following addresses had permanent fatal errors -----
user@reciever.com
(reason: 553 <sender@adress.com>... No such user here)

----- Transcript of session follows -----
... while talking to receiver.com.:
>>> MAIL From:<sender@adress.com> SIZE=27
<<< 553 <sender@adress.com>... No such user here
501 5.6.0 user@receiver.com... Data format error


I've checked all the obvious:
DNS records are all there (it used to work, and still does for some senders), the domains are mentioned in de relay/recieve boxes in the raq's mail settings.

The raq's main domain is moved, i did'nt bother to enter a new domain (until today when this problem got worse), could it have anything to do with this ? some DNS mixup ?
Is the main domain of any importance to receiving mail on other domains on the same server ?

Any other ideas are very welcome i getting desperate :bawling:

Ok, I have know Idea whats up with your system. But just curious if you have recently installed Open Webmail???? I have noticed a on slaught of unexplainable email problems with my server since we switched from Neomail to Openwebmail. I thought I would see if maybe this was true for you as well.

i've noticed an onslaught of mail problems AMONG many others since doing the OS2 update.


grrrrr. cobalt.

I did not install webmail or neomail.

Does anyone have a clue in wich direction to search ?

I'm having the same problem. I'm info@thedomein.com doens't work. But adriaan@thedomein.com (that's in another virtual host) DOES work.

Prittry strange hé?

I hate to be the one to ask the obvious but.... did you either create a user "sender" or add "sender" to your email aliases?

The "no such user here" is a well known error message and it usually means just that: the user to whom the email is addressed has not been created (does not exist).

It's either that or you have a problem with your alias database but the first option is more realistic.

I've lost it completely now.

I can send from my kabel account (Chello), but can't from my other raq.
Although i can send messages to anyone NOT on this particular server.

I guess its a DNS issue.

So i can't send mail to a particular server1 using an account from another server2, but i can from my providers server.
These servers are not in the same datacenter (not even on the same continent).

But from server2 i can send mail to anyone else in the world
:confused:

Luckaly i'm getting only few complaints from accounts on server1, so most people CAN send to it.

Would it be wise to give a email adres here so you can all test it ? i can delete the account afterwards ?

I did a little more testing, mailing to username@domain.com works perfectly, mailing to mailalias@domain.com doesn't work. ("User unknown")

How can I fix this??
