X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=6ccd335d2d7cea4f82a19b68f8c6965c773480b3;p=matthijs%2Fservers%2Fdrsnuggles.git exim: Use the external DNS name in HELO commands. The hostname of the mail vserver is not in public DNS, so some smtp servers reject a HELO command that uses it. This change makes sure that the hostname of the vserver host is used in HELO command, which is the external hostname to use for reaching the mail vserver. --- diff --git a/etc/exim4/conf.d/main/main_config b/etc/exim4/conf.d/main/main_config index 771d2b6..fd84263 100644 --- a/etc/exim4/conf.d/main/main_config +++ b/etc/exim4/conf.d/main/main_config @@ -31,8 +31,10 @@ hostlist dont_reject_spam_hosts = katherina.student.utwente.nl : kat.student.utw # can come from any vserver, just use our main hostname. qualify_domain = drsnuggles.stderr.nl -# Let exim know how the rest of the world will try to reach us. -hosts_treat_as_local = drsnuggles.stderr.nl +# Let exim know how the rest of the world will try to reach us.
