Actually just released an application which has a script that will relay mandrill inbound webhook to smtp. https://github.com/huoy/webbermail

A) In Mailserver / SMTP / Hostname (FQDN): change the setting to: SmartHost.local and eliminate anything listed in Additional Domain. If you do have any domains listed in either location, mail for those domains will NOT be sent out to the Internet. Instead, Mail Server (actually Postfix) will look to see if there is a LOCAL USER - admin, your login user ...

If this is valid mail, it is entirely possible your organization isn't identifying itself properly to avoid being classified as Spam. Reference Fighting Spam - What can I do as an: Email Administrator, Domain Owner, or User? for information on ways to fight this. My biggest recommendation is to use SPF records to say who/what can send email as your domain. ...

You need to use the domain apex for the MX. Think of an MX record logically as "mail for pro.lan should go to this server". So, for example: smtp.pro.lan. IN A 192.168.84.30 pro.lan. IN MX smtp.pro.lan.

If you want to connect MS Outlook to Zimbra using MAPI then you need a Zimbra 8.6 Network Edition which requires a license. If you already have a Network Edition server then you want to install the Zimbra Outlok Connector to connect Outllok to Zimbra through MAPI. Admin doc User doc If you want to use the open source version, then you can't use MAPI. You ...

Removal of dynamic IP addresses from the Spamhaus blocklist is not desirable. The RFCs support such blocking, and these blocks allow a lot of spam to be blocked. Spamhaus documentation covers this blocking set. I commend your ISP on providing their dynamic IP addresses to Spamhaus and putting a block on their removal. Properly configured mail servers ...

This is in the comments, but posting out as the answer I've not used that firewall before but on netgears there is normally a screen for outbound rules. You need to make an outbound rule . Lan User (LAN IP of mailserver) Wan User (Any) NAT IP (Enter the 118 address). Effectively what has been done is to create an outbound Nat on the firewall. So ...

In the case you've described, the mails did not originate at your mail server, so they will not affect your mail server's reputation. The SPF record allows any mail server which is configured to check them to reject such messages or mark them as spam, but not all mail servers check SPF records, and some which do check them don't actually do anything with ...

emailsecuritygrader.com reports you have a syntax error at your SPF record. Take a look to this: http://www.openspf.org/SPF_Record_Syntax

Where are you defining the Mandrill API key? I think you are missing smtp_sasl_password_maps directive in main.cf. Please see the following: Can I configure Postfix to send through Mandrill?

The problem here is that you configured your server so that it should relay any outbound email to a server, namely smtp.mandrillapp.com. That server, in turn, is not accepting to relay your mail. I don't know this company, but my guess is that they only relay mails from authenticated customers, and your are not logging-in. You should probably have ...

You appear to have hit a long-standing issue in Android. In particular Android will only load the autodiscover XML over HTTPS. If you serve it over HTTP then Android will refuse to even attempt to use it. As described in the bug, Android does not use DNS SRV records to locate mail services.

The error message from AOL seems to indicate that indeed your IP address was blocked. You could try to check using online databases such as senderbase if your IP has a listed reputation. Unfortunatly, it is the nature of banning that you cannot do much more to resolve it than to try to appeal to the relevant provider (in this case, AOL) and explain that ...

From the top layer perspective, Postfix relies on libc resolver to do DNS lookup (including RBL), so the the behaviour would depends on the library. For example, postfix will alwasy do lookup via NS server defined in /etc/resolv.conf. If the NS server has caching mechanism, then postfix will get the cache result too. This is also happen if your provider has ...

I actually ended up getting an answer to this on my own - Outlook determines this from the Sender header rather than the mail-from header (which in our case didn't have the display name attached). We're going to be adjusting this internally.

You've got a PTR record mapping 162.254.149.186 to host2.sparkdojo.com, which is fine, But there's no A record for host2.sparkdojo.com, so the lookup the other way is not working. You need both of them to work.

First you need to block all script that using mail() to send the email to postfix. To do that, you have many options. You can use authorized_submit_users parameter from postfix to limit sendmail command for user root only. Put below line to main.cf authorized_submit_users = root You can use disable_functions feature from PHP to disable mail function. ...

That would be highly inadvisable, or, to put it simply, just plain wrong. Just because the secondary server can connect to the primary doesn't mean one or more legitimate SMTP clients can connect to the primary. Multiple MX servers are primarily designed to handle routing and connectivity issues (and the weighting parameter is there to help hint at the ...

Well, I've performed a thorough diff and found these settings, which make Exim receive email: /etc/exim4/conf.d/main/01_exim4-config_listmacrosdefs: comment out or remove this block (lines 64-66): .ifdef MAIN_LOCAL_INTERFACES local_interfaces = MAIN_LOCAL_INTERFACES .endif and place this instead (note the dot between the address and the port, this is ...

Okay, I got the answer. osTicket had been set to use SMTP, but it had been set to do so without authentication. When it was set to use authentication the email address was displayed correctly in outgoing mail. Also it will show any email address that you put in the Email Address field at the top of the email settings which answers the second part of the ...

You could block all unestablished outgoing packets on all ports but the one port to the one destination you permit mail google:587 for example. That would stop spam and force authentication. A less good solution is to permit only non encrypted email via any IP enforced with deep packet inspection, but most people want encryption. Most ISPs block port 25 ...

In fact, the problem is simple: your JAMES server is running in an instance that's probably geographically far from where you usually are when you log in to your Gmail account, so it appears to Google like someone is trying to break into your account (after all, how can you be logging in from California and Virginia within a couple of hours of each other?). ...

Can anyone explain how this: https://www.ssllabs.com/ssltest/analyze.html?d=mail.luken-tech.pl&hideResults=on shows "Assessment failed: Unable to connect to server" SSLLabs only support HTTPS Testing.
