Re: Problem with sending email to Yahoo, MSN, Hotmail and AOL accounts
I have also had issues with mail delivery with the big email services. The best ways I have found to improve delivery performance:
- DKIM and SPF

https://mandrill.zendesk.com/hc/en-us/articles/205582267-What-are-SPF-and-DKIM-and-how-do-I-set-them-up- <https://mandrill.zendesk.com/hc/en-us/articles/205582267-What-are-SPF-and-DKIM-and-how-do-I-set-them-up->
- DMARC
- STARTTLS on port 25 for SMTP
- Proper TLS certificate chains
- reverse DNS for mail hostname
- properly set EHLO/HELO hostname
The HELO name is set in smtpserver.xml in 3.x in this XML block:
<!-- This is the name used by the server to identify itself in the SMTP -->
<!-- protocol. If autodetect is TRUE, the server will discover its -->
<!-- own host name and use that in the protocol. If discovery fails, -->
<!-- the value of 'localhost' is used. If autodetect is FALSE, James -->
<!-- will use the specified value. -->
<!--
<helloName autodetect="true">myMailServer</helloName>

Set the hostname in this configuration block to your mail server name.

It appears I have a couple of serious issues and a couple of minor ones, but I have not found any joy in solving all of them by searching on the internet. The SpamAssassin reported the following -

I read everything I could find on the Apache web site but only found a couple of bits and pieces of info, nothing I could grok however. Will it even work with my version of James - 2.3.2?

>> I have had many problems with gmail, yahoo, hotmail, etc bouncing my emails. To say they are picky is an understatement. If there is ANY problem with the structure of your email and/or your email setup, domain, dns, server IP address, and a bunch of other things , they are going to bounce it (with zero useful info to explain why). They also bounce according to how many emails you've sent depending on how 'spammy' they think the email is. They may let a few in. But if you send 20 'suspect' emails in a day, they'll start bouncing for a day or so, then let it start passing thru again.

A good place to start is mail-tester.com <http://www.mail-tester.com/> Go to the web site and they'll give you a temp email address that you can send an email to. After you send it, click the link to analyze the mail. They will grade your email including the sending server parameters and tell you how 'good' your email is. With detailed explanations of what is wrong. My initial score was pretty bad. It took some time and was a royal pain to fix all of the issues. But I finally got the coveted 100% grade. It appears gmail and others are finally happy with me and are letting my emails thru.

>>> Hi, I am running James 2.3.2 on a Linux (openSuSE 12.3) and recently encountered a problem that I am unable to resolve. I use the maillist mailet to manage a mail list for a number of users and now all emails being sent by the users to accounts at AOL, Yahoo, MSN, GMail, and Hotmail are bouncing. This is something new and I have not made any changes to James's configuration for a very long time. I have checked forward checking on reverse DNS look ups both via dig and on several different DNS checking websites and that is working correctly. The log files don't give me much help as far as I can decipher them, the mailet logs just indicate that there was a problem such as -

I admit I do not know enough about these log files to be able to make any sort of correlation between the errors I see in the mailet log files and these other errors being reported in other log files. So I am out of my depths, any kind guru want to help me resolve this?
