Ports Configuration

Same for all accounts

Example for Posteo

Server name: posteo.de
Username: [email protected]
Password: Your personal password

Important: The connection to Posteo is always encrypted (STARTTLS, TLS or SSL).

The outgoing mail server (SMTP) requires authentication.

In case your email client asks: The password will be checked “normal” or “plain”. The password can also be transmitted unencrypted, because it is requested over a connection that is already encrypted.

The port settings depend upon the type of encryption:

Outgoing mail server (SMTP):
With STARTTLS using port 587, or
with SSL/TLS encryption using port 465

Incoming mail server (IMAP):
With STARTTLS using port 143, or
with SSL/TLS encryption using port 993

Incoming Mails

Video explains about the problem for Thunderbird Connect to Mail Server. In next rows of the table, we can see different ways how to fix this problem.

We use encrypted IMAP Protocol.

We prefer to use, SSL/TLS 993 port on Posteo for example.

To add security to some existing protocols (e.g. IMAP, POP, etc.), it was decided to just add SSL/TLS encryption as a layer underneath the existing protocol. However, to distinguish that software should talk the SSL/TLS encrypted version of the protocol (implicit TLS) rather than the plaintext one, a different port number was used for each protocol. So you have:

  • IMAP uses port 143, but implicit SSL/TLS encrypted IMAP uses port 993.
  • POP uses port 110, but implicit SSL/TLS encrypted POP uses port 995.
  • SMTP uses port  25, but implicit SSL/TLS encrypted SMTP uses port 465.

The hosting provider forced us to use own subdomain, not their. So there is no any change, just the hostname.

Authentification and Security

Oath2 vs. Normal PW

  • Oauth2 is token based authentication .
  • Normal PW is an old method of authentication and less secure, but works perfectly.
  • Many of the email providers doesn’t offer Oauth2 authentication.
  • If possible, use Oauth2, if not Normal PW is fine.

SSL and TLS both provide a way to encrypt a communication channel between two computers (e.g. your computer and our server). TLS is the successor to SSL and the terms SSL and TLS are used interchangeably unless you’re referring to a specific version of the protocol.

STARTTLS is a way to take an existing insecure connection and upgrade it to a secure connection using SSL/TLS. Note that despite having TLS in the name, STARTTLS doesn’t mean you have to use TLS, you can use SSL.

Setting SMTP Params

  • Configure outgoing server for Posteo
  • Rename Outgoing SMTP Server so that no mail address is visbile
  • Choose SMTP Server for mail accounts with Identities
  • Choose SMTP Server to accounts that do not have identities
  • Question: How to disable sending from harry mail?  –> not useful link
  • Team found a useful link for disabling sending emails from Harry mail
  • SMTP for ecoblogs mail
  • testing: send mail to yourself

Video Name:  Outgoing SMTP Mail and Identities

The video explains 3 things:

  1. Set Default Identity 0:00 –> 0.50
  2. Do use Default for Outgoing Server, but use the RIGHT one for each account.
  3. Define a new outgoing Server (SMTP) atarts at 0:50
  4. Start -> 0:50 Outgoing Mails
  5. 1:00 -> end Account Settings and Identities

Outgoing Servers not show Email

1. Cannot Distinguish Emails.

2. Do not show Email addresses.

  1. We use a Gmail, SNB, etc.to distinguish

2. Do not show Email address in description.

Harry not allowed sending Mail

Harry shall not be able to sent mails.

Create dummy outgoing mail for Harry with wrong port. The port for Posteo is 587, we just put 586.

Outgoing Server Harry –> Make Error

Harry Hallers should never send mail


One option is with the confirm address plugin.

A better option is to use wrong outgoing server.

Superozi vs. Gmail

Why SuperOzi?

SuperOzi is a bulgarian cheap mail service. We use it because it is cheap and it is working fine so far.

SuperOzi price is $1.50 / month for unlimited email accounts.

Why not Gmail?

Gmail is the best email provider, but it is not cheap.

One account at Gmail costs about $12 / month which is a lot if you use only Gmail and not the rest of their services like Drive, Sheets etc.

SuperOzi how it works?

All access for superozi are in Keepass.

The problem was in wrong server settings in Thunderbird. This was for all Gmail accounts. The smtp and imap server name was only gmail.com.
This is wrong, because different IP addresses are for the different services.George told team to remove IMAP and SMTP from doc page for server, But they removed it from the settings, too.
