The error is effectively telling you that the mailbox to which you tried to send the message doesn't exist.

You mention that you've confirmed the user exists. What have you done exactly? Have you also checked for forwarders or filters that might be interferring somehow?

You can also find out more from the main Exim log. From shell:

Code:
cat /var/log/exim_mainlog | grep [email protected]
That command will return all lines from Exim's main log that contain the text '[email protected]', which should include the errors you need to find.

I have a similar problem.

One of domain of my server has the mail failing.

I proved the cat and this say that "rejected RCPT <[email protected]>: Unrouteable address"

When i send a email to this account i recieve a Mail Delivery that say:

host XXX.XXX said: 550-"The recipient cannot be verified. Please check all recipients of this 550 message to verify they are valid." (in reply to RCPT TO command)


Any solutions? can i repais this problem?

I had this happen to a couple accounts, apparently at random, about a week and a half ago. I was never able to figure out the actual cause. In desperation and trying a /scripts/upcp --force and /scripts/fixeverything fixed all but one of them. The account that it didn't fix was for a parked domain. In that case, I finally just deleted the parked domain and re-created it. I was fully expecting to have to then re-create the a-mail addresses for the newly (re)created parked domain, but to my surprise, after deleting and re-creating the parked domain, the accounts were still there and now worked.

I'm sure someone wiser than me would say, 'what the heck did you do that for, when all you needed to do was...', but I couldn't find any other solution and was grasping at straws.

BTW... the accounts I was unable to send mail to during this period would also not let anyone log into them either via pop, imap, or webmail.

Keep in mind, what I did was done in desperation and worked for me. I wouldn't really recommend it for anyone else. I'm just relaying my experience here.

I have similar random problems.


I wonder if it is related to having "Verify the existence of email senders." checked in WHM... Though I've been told that is important to stop spam, I don't want it to stop outgoing mail.

Here are a copy of the message. It seems to come immediately as a message from the server to Outlook, which generates an email such as:

Here is piece of the exim mainlog
2006-11-08 18:40:15 H=((SENDING IP/NAME)) F=<((SENDING EMAIL ADDRESS))> rejected RCPT <((RECEIVING EMAIL ADDRESS)): ((SENDING IP/NAME)) is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.
I believe this particular error is now fixed by having outlook perform full log-in authentication on the sending clieint, though this wasn't required before.
