Forum activation problem - invalid HELO

Sun Sep 25, 2011 8:57 pm

Hi,

I had problems with activation mail send by this forum. The e-mail is sent via mail server with invalid (from the point of view of many mail server admins) HELO/EHLO command:

Sep 25 19:42:26 *** postfix/smtpd[26397]: NOQUEUE: reject: RCPT from tuncis.mt.lv[159.148.147.201]: 450 4.7.1 <tuncis.localdomain>: Helo command rejected: Host not found; from=<support@mikrotik.com> to=<***@***.pl> proto=ESMTP helo=<tuncis.localdomain>

I guess e-mail is sent using php mail() function which sets HELO to current machine hostname.

Please, correct the hostname to an existing one (DNS-wise) so that mail recipients know who does send the mail and can do SPF, RHSBL checks.
