![]() ![]() Welcome messages can be anything such as "Welcome to my Dungeon. Which suggests it should be used as a method to HIDE public identification rather than highlight it. " One reason to change the welcome message is to make it harder for other people to determine what server software you are running." I never had it matching anything like the host it represents and never had consequences. I have long understood that the Welcome message doesnt matter and has no bearing on reputation (and it is only MXToolbox that 'suggests' they should meaningful to matching dns records). SMTP Welcome message: "10.10.10.10. ESMTP"ġ: SMTP Welcome message must match A and PTR records = FCrDNSĢ: SMTP Local hostname = EHLO greeting must match hostname in MX record for domainģ: SPF record must cover server for domain "mydomain.tld"Ĥ: DKIM record must match email signature for "mydomain.tld"ĥ: DMARC must have positive SPF result and positive DKIM result. My PTR does not match my hostname nor my domain and still I check all the boxes. I know the project isn't active, but that would be ideal. I would think if HMailServer already has a rule of binding to an IP address that it should be possible to add a feature to use a different local host name depending on the header. I thought a best practice would be to do a local host name to match our reverse DNS. We already have 2 servers that don't have issues anymore because they have been running for over three months. ![]() These are fresh IP addresses which need to get good reputation. If you were sending a message you would be communicating via SMTP with the server.That is not true. I just tried to send the email twice and got 2 different logs output: Try again or contact your network administrator. The message could not be sent because the connection to SMTP server was lost in the middle of the transaction. First Thunderbird after about 20-30 secs says:Īn error occurred sending mail: The mail server sent an incorrect greeting: Cannot connect to SMTP server 78.109.160.200 (78.109.160.200:25), connect error 10060. ![]()
