<div dir="ltr">Hy Tony,<div><br></div><div>You need a PTR DNS Record for your IP and this PTR Records <b>MUST</b> match the hostname from mailserver. This PTR Record isn't related to your server, but to your server provider. So you need to ask them.</div><div>But if "Server without name" only means, that Postfix isn't using a Hostname: <a href="https://rudd-o.com/linux-and-free-software/setting-up-a-mail-server-using-postfix-in-5-minutes">https://rudd-o.com/linux-and-free-software/setting-up-a-mail-server-using-postfix-in-5-minutes</a></div><div><br></div><div>But: There is a reason, why such Mails are blocked. (<i>And also will blocked with short information to sender on all server I manage</i>)</div><div>If a ServerAdmin is not able to configure a Mailserver, there cannot be any important mails from this server and admin mostly also cannot monitor if the server is sending spam or someone tries to BruteForce a SMTP login.</div><div>Sounds hard, but otherwise SPAM will flood our servers.</div><div><b>To be fair:</b> In the last 1-2 years the administration of Mailserver is getting harder and harder and is a very time intensive task. I'm happy about every client, which use external Mail Provider, like Office 365, GMail, etc.</div><div><br></div><div>You/your client should consider to use something like <a href="https://www.mailgun.com/">https://www.mailgun.com/</a> for mailsending. (from CRM)</div><div>Last month I found them and be very happy about the packages they provide (<b>Also free one</b>). Not too expensive and very developer friendly. (And we don't get any SPAM problems from their used IPs in last 4 weeks ~8000 Mails )</div><div><br></div><div>Regards,</div><div><br></div><div>Stefan</div><div><br></div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br><span style="font-size:x-small">--</span><span style="font-size:x-small">--</span><br><b><font size="1">Freelancer@Webdevelopment</font></b><br><br><font size="1">Web: </font><a href="http://www.stefanwarnat.de" style="font-size:x-small" target="_blank">http://www.stefanwarnat.de</a><br><font size="1">Xing: </font><a href="https://www.xing.com/profile/Stefan_Warnat2" style="font-size:x-small" target="_blank">https://www.xing.com/profile/Stefan_Warnat2</a><br><font size="1">LinkedIn: </font><a href="http://www.linkedin.com/pub/stefan-warnat/6/827/820" style="font-size:x-small" target="_blank">http://www.linkedin.com/pub/stefan-warnat/6/827/820</a><br><font size="1">eMail: <a href="mailto:kontakt@stefanwarnat.de" target="_blank">kontakt@stefanwarnat.de</a></font><br><br></div></div></div>
