This error occurs when the sending email is rejected because the username cannot be found or is not accessible by the server. There are several reasons why you would get a "550 No Such User Here" error.
Mail file permissions are not readable or are incorrect. The email address was typed incorrectly. MX records are incorrect ( pointing to the wrong server ). Email does not route correctly ( Remote / Local domains ). This errorthe semantic validity of the data in an incoming SMTP message. Verification failures can cause the message to be rejected, or they can just be logged. Other types of control over incoming mail are discussed in subsequent 550 no such user here google apps chapters. The -bh command line option can be used to run fake SMTP sessions for

the purpose of testing verification options. 45.1 Host verification The name of the sending host is looked up using gethostbyaddr() if its IP address 550 no such domain at this location barracuda matches host_lookup (which is unset in the Exim binary, but in the default configuration file is set to match all hosts). In some environments this might involve an expensive DNS lookup, so some sites may wish to disable http://www.inmotionhosting.com/support/email/bounceback-errors/fixing-no-such-user-here it. However, an SMTP server for local desktop systems (which are frequently misconfigured) can normally look up their host names cheaply. This improves the contents of Exim's logs by including the correct host names. Even if its address doesn't match host_lookup, a sending host's real name is looked up from its IP address if the argument it provides for the HELO or EHLO command is the local host's own name, or the name of one of its http://www.exim.org/exim-html-3.20/doc/html/spec_45.html local domains, which seems to be a fairly common misconfiguration. A host name that is obtained from looking up the sender's IP address is placed in the $sender_host_name variable. If no lookup was done, or if the lookup failed, that variable is left empty. Failure to look up the sending host's name is not of itself an error, nor is it by default an error for the name given in the HELO or EHLO command (which is placed in $sender_helo_name) to be different. The RFCs specifically state that mail should not be refused on the basis of the content of the HELO or EHLO commands. However, there are installations that do want to be strict in this area, and to support them, Exim has the helo_verify option. Even when this is not set, Exim checks the syntax of the commands, and rejects them if there are syntax errors. It can be made less strict by unsetting helo_strict_syntax (which allows underscores to get through) or by setting helo_accept_junk_hosts (which permits certain hosts to send any old junk). When helo_verify is set, a HELO or EHLO command must precede any MAIL commands in an incoming SMTP connection. If there wasn't one, all MAIL commands are rejected with a permanent error code. In addition, the argument supplied by HELO or EHLO is verified. If it is in the form of a literal I

Here is a simple article on how to configure that under Ubuntu, which has a split file type of configuration (as debian) and so differs from the official one. share|improve this answer answered Apr 22 '11 at 12:54 Mr Shunz 1,7171413 add a comment| up vote 1 down vote Well, exim thinks that the domain of the receiving email is not local (so it should relay it) and correctly is denying to be a relaying host. You have to add your domain to local_domains like this: domainlist local_domains = @ : localhost : mydomain.com share|improve this answer answered Aug 2 '11 at 7:55 Jorge Nerín 88868 add a comment| up vote 0 down vote After several hours of working in circles I stumbled upon the answer that worked for me. It didn't matter how many permutations of dpkg-reconfigure exim4-config I tried, adding in entries for dc_relay_nets or dc_relay_domains or direct edits of exim4-local-domains.txt. It turns out there is a file named exim4-relay-mail-from-this-list-of-ip-addresse
