Re: Prevention of sending authentication via plaintext on port 25.

Here I am, replying to my own post again. What I said in the prior post wasn't entirely true. I realized that I used the wrong password in my prior attempt. I am still granted access to the SMTP service after authenticating in plaintext on port 25. So I'm somewhat confused how to

Re: Prevention of sending authentication via plaintext on port 25.

I suspected that was a typo. I figured it out. I made those changes, when I attempt an AUTH LOGIN, I get back "535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6" which seems to be appropriate. So the user is no longer rewarded with access to the SMTP services when they attempt to connect

Okay, I'm made some exciting progress and I am grateful for the help. I will show to people how I got this working At first thought, I figured that it would simply be the IMAP password used by Dovecot to access my mailbox. Not exactly true... I did some digging in some blogs and the

Re: SMTP Error with Thunderbird with remote Ubuntu Server 16.04

Okay, Victor, thanks for the stats in the second email! That is quite interesting to read. I have only recently (this summer) heard of LetsEncrypt.org. Up until that point, I had expected that I was condemned by powers-that-be to buy a key annually forever. Oh yeah, I love the "smoke and

Re: SMTP Error with Thunderbird with remote Ubuntu Server 16.04

Okay, I am already using letsencrypt.org for my port 443 traffic. So once I have it extended to also cover SMPT on port 587, would it be acceptable to disable port 25, or is port 25 still needed (perhaps to suggest to clients that it isn't accepting any traffic except 587) I have to admit, I

Re: SMTP Error with Thunderbird with remote Ubuntu Server 16.04

I should make clear in the post that u...@example.com is the IMAP mailbox name and that m...@example.com is a virtual alias. This machine hosts about 8 domains and has, I think, three mailboxes. I am the sole user of the email system. On 11/28/2016 at 11:58 AM, rich.gre...@hushmail.com wrote:

Okay, I am really curious how this works then. Good catch on the 'www' test. I winged it without reading the manpage. I've never known a good starting point for learning DNS, so that is definitely a weak point. So, now that the DNS is out of the way. I'm going to dig deeper here. When I

SMTP Error with Thunderbird with remote Ubuntu Server 16.04

Hello, First, email has been working fine on this server for past several months while using the Squirrelmail web client located on the same server. I am needing an alternative method to access mail services and decided, on a whim, to try Thunderbird. Thunderbird interacted with the Dovecot

Re: SMTP Error with Thunderbird with remote Ubuntu Server 16.04

Okay, I accidentally sent this half-composed. But yes. I was able to send via SMTP, but only if my destination address was on my machine (which is probably good) Maybe since I sent this, I let people deliver their opinions on if this is an MX record issue first. Thanks Rick On 11/28/2016
