This is more than likely the case. Most providers have in effect a spam and virus filter, so before the original email is delivered it will be caught and discarded / not forwarded. Is this an IP address dedicated to you? If not, others using the IP address (example case, shared hosting) may be contributing towards the negative reputation.

You also need to be sure you have valid DKIM and SPF records setup for your domain. You can create a TXT record that looks like this: google._domainkey So fully resolved that would be google._domainkey.yourdomain.com. Now for DKIM, you need to find your key in googles admin dashboard for your email: v=DKIM1; k=rsa; t=y; ...

I recommend signing up for a free account on SenderScore.org. They have some very useful tools for diagnosing why your mails might be being rejected.

As I understand this, the problem is that your OpenSSL upgrade has made you intolerant of other's short DH key lengths, in order to protect the conversation against the Logjam attack. That's why increasing your DH key length (openssl dhparam ..., etc.) did nothing to help, whilst turning off TLS did. Obviously, what we'd all like is a flag to OpenSSL like ...

First of all I would be careful to follow RFCs and alike when changing things like this. I'm not aware of anything that regulates bounce messages to this detail, but it might exist. There are different templates for failures and delayed mail. See the Postfix documentation for more information about failure_template and delay_template. This is the default ...

This sounds like there is a connection document missing, which explains that Server 02 should route emails to server 01. Did you have any connection documents in place? If not please create a connection document to route the emails to your master SMTP Server. This one might help (however do not fully know your environment): Connection Type: SMTP Source ...

You can pipe output of multiple command into sendmail input. If the code below does not work for you the name (command) shell you use. ( # Command 1: "here document with headers and initial body lines cat << END To: toemail Subject: Test X-APP-VOLT: Yes Hope this works! Email Body line 1 END # Command 2: uuencode file cat file | uuencode filename ) ...

DNS data is cached. If you didn't reduce the TTL before the move, then entries can be cached until they time out. If you can configure your old server to defer rather than reject email arriving from the Internet, the messages should eventually be delivered to the correct server. Alternatively, and likely more appropriately configure the Exim server to ...

I went into a bit of a wiki-hole on this one, based on an off-hand comment that Outlook.com supports this from a source article for a linked question (it doesn't, really). Outlook.com obviously runs on Exchange at some level, so I simply had to satisfy my curiosity. If you're an Exchange admin, you can create a mail contact for whatever you want at your ...

Based on main.cf, Postfix will connect to socket private/auth_dovecot relative to /var/spool/postfix. Unfortunately, based on dovecot -n output, dovecot only provide socket in /var/spool/postfix/private/auth. So, this misconfiguration explain why postfix throw error No such file or directory

This is a an old post. However, this may useful to some one else. Based on this link https://theblackdragon.wordpress.com/2011/06/07/ssmtp-and-aliasing-the-to-address/ Ensure mailx is installed on your system ( try mailx -? ) Edit /etc/mail.rc like this: alias root root<root@myremoteaddress.be> Now, mails to root@localhost will be sent to ...

Setting up a postfix server that accepts this domain might help with what you are looking for. Any low cost VPS server should be sufficient.

Generally speaking the receiving server will look at the client that has connected to it and asked to deliver some mail. The first part of the SMTP protocol is a greeting command (HELO or EHLO) where the client can identify itself. Most email servers will take that claimed identity and compare it to the PTR record for the client's IP address. The client ...

You'll still need to configure something to deal with email. The easiest way is probably to configure whatever MTA you're using so that it changes apache@testserver1.localdomain (the email address that php ends up using) into whatever mail address you want to use. Since you seem to be using Postfix, you should check out this part in the official Postfix ...

This happens because your host has a name that somewhat resembles an IP address, for instance 62-210-247-11.rev.poneytelecom.eu To fix the problem, you need to do two things: Give your host a proper hostname, which is a fully qualified domain name. For instance, mail.example.com. Note that it must not be a "naked domain". On CentOS 7, edit /etc/hostname ...

The short answer is no. Assuming you're using Outlook with MAPI (using IMAP or some other protocol could only tell you that the message was retrieved by a mail client, most of which sync automatically on a schedule anyway). Even if there were a way to identify when the email had been marked as read (and I doubt that there is, but can't say for sure), it ...

This doesn't seem to affect just IOS, it may be that your carrier (or carrier settings for your phone) is cutting off the message during the send, meaning that an error isn't coming from the Exchange server to the iPhone, so your iPhones are trying over and over again. Try reducing the data cap to something like 7340032 (7 MB) or 6291456 (6 MB) and see if ...

Disabling ipv6 on centos 6.5 seems to have removed this issues.

You can specify the path to php.ini passing option --php-ini FILENAME to the php executable. Try again giving the path to the php.ini used by the webserver.

You can use any third party monitoring software tools like PandoraFMS to monitor any services and virtual machine uptime. You will get many options to monitor various services like: MS SQL server (on port 3306), MySQL server (on port 1433), IIS/Apache web server (on port 80) and Server Uptime (on time ICMP package - Ping). You can also set email ...

Not 100% sure what's your problem but this is might going to be fix it. I was using freenom for free domain names (.tk,.cf etc.) and then, I was using Cloudflare as an proxy and an dns server to add every dns setting I had to use (A, AAAA, MX, etc.).

I'm not aware of "outlook autodiscovery" working at all without the "proper" DNS TXT and SRV records in your domain. But these are non-standard and may differ depending on how you, your ISP, or your hosting provider have configured your email SERVER and which server it is. here are some samples of ISP, Microsfot , and tech help blogs showing the variety ...

I'm not aware of "outlook Autodiscovery" working properly without having hints in the domain DNS. I assume you are talking about an "Exchange Server", but can you be a bit more specific about which "Android's default email client", I have 3 in front of me and they each have a different "default" email client installed. You also don't mention your server, ...

Take a look at https://technet.microsoft.com/en-gb/library/hh529949(v=exchg.150).aspx There is an interesting line at the bottom of that page that implies the effective maximum limit is about 33% less then the limit you have configured. Given the default for active sync is 10mb and you are seeing problems around 7, that would make sense. Try increasing to ...

The MailDir tree should be owned by the user that is getting the message delivered. You can fix the home directories with this little script. cd /home for dir in *; do [ -d $dir ] && chown -R $dir $dir done This will reset each users home directory tree to be owned by that user. In the rare case that the home directory name does not match ...

Try increasing the uploadReadAheadSize in IIS as in the following example (change the size to the one that you need): C:\Windows\System32\inetsrv\appcmd.exe set config -section:system.webServer/serverRuntime /uploadReadAheadSize:"10485760" /commit:apphost C:\Windows\System32\inetsrv\appcmd.exe set config "Default Web Site" ...

I ran a quick test of my IPad with TLS1 disabled, and was unable to connect to my mail server. My first question would be why is your e-mail server in your PCI-DSS protected zone. You shouldn't be emailing credit card numbers and other protected data in a form that requires PCI compliance. Sending such data by email will break your compliance. Move the ...

It depends on your mail server. The way Exchange does this is by configuring its SMTP domain(s) as "internal relay", which basically means "try to find the recipient in this system and if it's not found route the message somewhere else", while instead the standard configuration of an "authoritative" domain is "try to find the recipient in this system and if ...

(Shamelessly copied from http://stackoverflow.com/a/29939735/32453) You can configure Ubuntu to prefer IPv4 over IPv6. This way you will be able to send emails and access IPv6-only sites. Edit /etc/gai.conf and uncomment the following line: precedence ::ffff:0:0/96 100
