i know this question has been asked before, but i really need a step by step guide to configure sendmail. The problem is that mail sent from a server (let's call it comarp.nicola.it) is not received by some recipients. I'm sending the mail through a php scripts that uses joomla Jmail class.
This is what i get from my mail log:
Apr 18 10:38:20 lamp sm-mta[8046]: STARTTLS=client, relay=comarp.it., version=TLSv1/SSLv3, verify=FAIL, cipher=AES256-SHA, bits=256/256
Apr 18 10:38:20 lamp sm-mta[8046]: p3IAcHeM008044: to=<eleonora@comarp.it>, ctladdr=<www-data@lamp> (33/33), delay=00:00:03, xdelay=00:00:02, mailer=esmtp, pri=150573, relay=comarp.it. [62.149.232.38], dsn=5.1.1, stat=User unknown
This is the log from the server that is refusing the mail:
2011-04-18 12:38:18 H=(lamp) [83.103.127.192] sender verify fail for <www-data@lamp>: The mail server could not deliver mail to www-data@lamp. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.
2011-04-18 12:38:18 H=(lamp) [83.103.127.192] F=<www-data@lamp> rejected RCPT <eleonora@comarp.it>: Sender verify failed
I think i have to configure something so that the sender is not www-data@lamp (maybe that should be something @nicola.it to make it work), but i'v lost the last four hours without finding a solution.
When sendmail starts it also says this message:
local host name (localhost) is not qualified; see cf/README: WHO AM I?
Thx in advance
