Hello, I recently had to rebuild my mail server. Unfortunately I am running into a little problem.
I seem to be able to DELIVER mail to my mail user account But when I try to _send_ mail I run into this error: ============================================================ [r...@cloud3:~ ] #:telnet cloud3 25 Trying 10.249.74.116... Connected to cloud3.newdom.com. Escape character is '^]'. 220 cloud3.newdom.com ESMTP Postfix (Ubuntu) This Is My Cloud! EHLO cloud3 250-cloud3.newdom.com 250-PIPELINING 250-SIZE 10240000 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN MAIL FROM: <bluethu...@newdom.com> 250 2.1.0 Ok RCPT TO: <bluethu...@externaldom.com> 554 5.7.1 <bluethu...@externaldom.com>: Relay access denied ========================================================== This is what is going on in my postfix logs: ============================================================= May 6 20:12:47 cloud3 postfix/anvil[4934]: statistics: max cache size 1 at May 6 20:02:47 May 6 20:12:56 cloud3 postfix/smtpd[4933]: NOQUEUE: reject_warning: RCPT from cloud3.newdom.com[10.249.74.116]: 504 5.5.2 <cloud3>: Helo command rejected: need fully-qualified hostname; from=<bluethu...@newdom.com> to=<bluethu...@externaldom.com> proto=ESMTP helo=<cloud3> May 6 20:12:56 cloud3 postfix/smtpd[4933]: NOQUEUE: reject: RCPT from cloud3.newdom.com[10.249.74.116]: 554 5.7.1 <bluethu...@externaldom.com>: Relay access denied; from=<bluethu...@newdom.com> to=<bluethu...@externaldom.com> proto=ESMTP helo=<cloud3> ============================================================== I am also including my main.cf and master.cf files for your perusal in the hopes that someone with a fresh set of eyes and more experience than I may be able to spot the problem In main.cf I have substituted newdom.com for the domain I am intending to setup, And I am using externaldom.com to symbolize a popular webmail service. kind regards
