i'm trying to send a mail from my personal server to another one ( the national health service so a bigger corporation ).
I've got a bounce :
Error Type: SMTP
Remote server (126.96.36.199) issued an error.
Remote server replied: 554 Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error, please contact the intended recipient via alternate means.
My mailserver is : hmailserver 3.1 1680. It's fully configured, and i've got all the antispam feature installed and configured.
I've got SPF record on mine domain ( and it's working and its ok ). My mailserver is not listed on the most popular dnsbl, i'm using greylisting,checking incoming mail on various dnsbl and surbl. PTR is configured "correctly "
The unique feature still missing is the DKIM signing and cannot enable ( due to godaddy's dns pannel editor with a 255 chars limits so cant add dkim sign) . Also the IP address of the server is a static IP address but is recognized as dynamic address due to italian poor infrastructure. ( most of the static ip address are recognized as dynamic ip but they're assigned statically.. ) . Infact the PTR is auto-generated by isp and cannot be changed.
what i'm missing? some one can help me?
i'm not a novice, in the past this issue was removed creating the spf record.
I think it's all related to the IP Address. Most of the italian little NSP having this kind of trouble recently..
