How To Get Hostname/ip Of Sending Mail Server From An Email
Nov 22, 2008
I know how to do this by analysing the headers, but we have a customers who doesn't believe what we are telling them.
Is there some kind of 3rd party service or script that we can point them to? So they can send an email to the service (or paste headers, or whatever) and it tells them who is the sending mail server hostname/ip?
(The problem is that this customer doesn't understand that all email sent from the server uses the same SMTP server hostname/ip. They are convinced that if they connect to "mail.their domain.com" then this is what is reported as the sending mail server/IP.)
I currently have a domain on Server 1 (Linux, Apache, Ubuntu, Matrix control panel).
This server does not have any spam filter, so I have moved all the email accounts to Server 2 (Linux, Apache, Fedora Core, Plesk) which does have a brilliant spam filter; and have changed the DNS record for mail.domain.com to the IP address for Server 2.
Emails are being successfully received on Server 2.
On Server 1, when an email is sent through SMTP to an address at that domain, it does not send it to Server 2, it gets delivered to the hosting account for the domain on Server 1. So what I am guessing is happening is that Server 1 detects the domain has an account on the server, and instead of looking up the DNS info for that domain, just assumes it is on Server 1.
What I need to do, is force Server 1 to send email for that domain to Server 2. Is this possible, and if so, how can it be achieved? If more info about the server is required for a solution please let me know and I'll provide what I can.
When a PHP script is sending a mail, there is added an return path in mail header. How to change that mail address in return path?
We are using Postfix and CentOS 6.5
Plesk is setting the mail address of the owner of the hosting account. When changing the owners mail address in Plesk, the return path is still the same and is not updated...
I have a client who is a media company and is interested in using a dedicated server in order to send their daily e-newsletters by email. The server will only host a script for handling the email distribution and email database.
They need to send approximately 20,000 emails every working day, in blocks of 5,000 emails. Each email includes an attached PDF file of 3Mb (this means less than 2,000Gb of bandwidth every month). They want each block of 5,000 emails to be sent within maximum 2 hours.
Please let me know the suggested configuration for a server to handle this email load.
our company is ordering a new dedicated server and we are a little unsure what we should choose as far as the full hostname and nameservers of this one server.
This server will have a couple different websites on it, but really, there is only one BIG website on it... let's call it abcd.com.
While most would pick a hostname of host.abcd.com for instance, if at all possible, we would like the domain name part of the hostname to be something different than abcd.com. We own a domain name that doesn't point to anything yet (unuseddomain.com) and we were wondering if we could use that domain in our hostname.. host.unuseddomain.com.
And instead of using abcd.com as the domain name for our own nameservers (ie. ns1.abcd.com, ns2.abcd.com), we would like to again, use the unused domain name we own (unuseddomain.com) for the nameservers domain name: ns1.unuseddomain.com, ns2.unuseddomain.com.
So...
Will this work? Is this perfectly acceptable?
And lastly...
Since the one website we really care about on this server (the one we got the server for in the first place) is abcd.com, is using the unuseddomain.com for the hostname and nameservers (as above) a bad choice in anyway regarding email deliverability? I understand that mail ISP's (hotmail, yahoo, etc.) do all kinds of checks on hostnames (PTR), etc... and we want to make sure that we aren't hurting ourselves in anyway by using an "empty" domain name that we own as our hostname's and nameserver's domain name.
For instance, if we send mail from the abcd.com account, it will use mail.abcd.com (1.1.1.1) as it's outgoing mail server... Hotmail will see this... do a reverse-dns lookup on 1.1.1.1 and see host.unuseddomain.com. See what I'm saying? It all will work, but will it toss up red flags?
I migrated a client from a Windows server to Linux and everything is fine except that mail sent to this client (say, example1.com) from a particular domain (say, example2.com) simply disappears and does not reach at all. Mail sent to that other domain (example2.com) from my new client (example1.com) is delivered correctly.
Incidentally, that other domain (example2.com) from which the mail is sent is with the hosting provider who was earlier providing services for my newly acquired client. Should I suspect anything? Or, is there a way to figure out what's happening?
I have MailScanner running on my VPS, but it isn't configured to filter at RBL level, only at Exim level, so I don't think this is the issue.
actually i want to know is this sending this email by my smtp server?

I have a server that I use to host my primary domain, and I have a cople Plesk servers, now I updated the hostnames of all the servers like
Code: s1.de.myserverplace.de
Now when the plesk server sends a mail it goes in spam always,
In the SPF records of the primary domain sits this
Code: myserverplace.de. IN TXT "v=spf1 a mx a:myserverplace.de a:s1.de.myserverplace.de ip4:148.251.100.157 ip4:144.76.163.46 ip6:2a01:4f8:201:81b8::60 ?all"
But when I actually send the mail in the headers of the received mail I get this.
Code: Received: from s1.de.myserverplace.de (s1.de.myserverplace.de. [144.76.163.46]) by mx.google.com with ESMTPS id p2si2158952wjy.73.2015.05.14.04.09.17 for <mymailtestacount@gmail.com> (version=TLSv1.2 cipher=ECDHE-RSA-AES128-GCM-SHA256 bits=128/128);
Of course, you need to past your own real values here. Then you need to launch this script every minute since the server restarted and follow the logs of what is happening there.
2) As we see you are using Microsoft FTP Service. The most probable reason for this is the issue with windows mail function - either the service itself is not reliable or it is just set incorrectly. Our administrator says that the issue with mail sending on this server happens quite often. So you can try to google the problem with the queue of windows mail function, for sure there must be some more advice as to how to resolve this.
It is possible that there is set a restriction on the order of the sending mail so when the queue is full, the mail stops sending.
Anyway that's all that we can advise you on this case because if the notification is sent at all then it means this function is working in our shopping cart and the issue is with something else.
i have problem in my server from 2 weeks ago server stop sending mail to yahoo and hotmail but to gmail send good without any problem i make SPF and add it for all domains after that mail worked Good in 1 day after that the problem come again
