    450 4.7.1 <hostname>: Helo command rejected: Host not found

    danielsch

      Hello,

       

      we use MEG 7.5.2 and we can not send mails to one customer, because the mail stays at the MEG queue with the information at the conversation log "450 4.7.1 <meghostname.local>: Helo command rejected: Host not found".

       

      It looks that the customer mail server does not accept the MEG hostname at the EHLO command. At the message conversation the FQDN of our MEG is used.

      That's the conversation log:

       

      Tue Mar 25 2014 09:16:08     DELIVERY         Delivery Attempt at Tue Mar 25 2014 09:16:07 GMT+0100

      Tue Mar 25 2014 09:16:08     DELIVERY         Performing delivery lookup for xxxx.xxxx@xxxx.de

      Tue Mar 25 2014 09:16:08     DELIVERY         Delivery lookup for xxxx.xxxx@xxxx.de resulted in 188.174.xx.xx:25

      Tue Mar 25 2014 09:16:08     DELIVERY         Delivery lookup successful, initiating delivery

      Tue Mar 25 2014 09:16:08     DELIVERY         Trying to connect 188.174.xx.xx

      Tue Mar 25 2014 09:16:08     DELIVERY         Connection successful

      Tue Mar 25 2014 09:16:08     DELIVERY     >     EHLO meghostname.local

      Tue Mar 25 2014 09:16:08     DELIVERY     <     250 mail.xxxx.net|PIPELINING|SIZE 81920000|VRFY|ETRN|ENHANCEDSTATUSCODES|8BITMIME|DSN

      Tue Mar 25 2014 09:16:08     DELIVERY     >     MAIL FROM:<xxx.xxxx@xxxx.net>

      Tue Mar 25 2014 09:16:08     DELIVERY     <     250 2.1.0 Ok

      Tue Mar 25 2014 09:16:08     DELIVERY     >     RCPT TO:<xxxx.xxxx@xxxx.de>

      Tue Mar 25 2014 09:16:09     DELIVERY     <     450 4.7.1 <meghostname.local>: Helo command rejected: Host not found

       

      What is the reason that this particular mail server not accept this?

      Why the MEG uses the local hostname and not the pubilc name for the HELO? I set the public DNS name at the welcome massage option.
