Let’s Try

Email providers today do a good job of filtering junk mail. 

You can do a better job with your own mail filters (

Tools » 

Message Filters

). You can choose to move/delete messages 

based on the occurrences of certain words in the From, To or 

Subject headers of the email.

• POP: pop-mail.outlook.com 

• SMTP: smtp-mail.outlook.com 

 

ƒ

Gmail 

• POP: pop.gmail.com 

• SMTP: smtp.gmail.com 

 

ƒ

Yahoo 

• POP: pop.mail.yahoo.com 

• SMTP: smtp.mail.yahoo.com 

The following settings are common for them:

 

ƒ

POP 

• Connection security/Encryption method: SSL 

• Port: 995 

 

ƒ

SMTP 

• Connection security/Encryption method: SSL/TLS/

STARTTLS 

• Port: 465/587 

Some ISPs and hosting providers provide unencrypted 

mail access. Here, the connection security method will be 

‘None’, and the ports are set to 110 for POP and 25 for SMTP. 

However, please be aware that most ISPs block Port 25, and 

many mail servers block mail originating from that port.

Thunderbird and SeaMonkey

Popular email clients today are Microsoft Outlook and Mozilla 

Thunderbird, the latter being the obvious FOSS option. Like the 

browser Firefox, Thunderbird is modern software and supports 

many extensions or add-ons. Unlike Outlook (which uses 

Microsoft Word as the HTML formatting engine), Thunderbird 

has better CSS support as it renders HTML messages using the 

Gecko engine (like the Firefox browser).

The SeaMonkey Internet suite bundles both the Firefox 

browser and Thunderbird mail clients, in addition to an IRC 

client and a Web page designer. SeaMonkey is based on the 

philosophy of the old NetScape Internet Communication 

Suite, in which the browser was known as Netscape Navigator 

and the mail client was known as Netscape Communicator. 

Because of certain trademark objections with Mozilla, 

some GNU/Linux distributions were bundling Firefox and 

Thunderbird as IceWeasel and IceDove. SeaMonkey became 

IceApe. This was resolved in 2016.

If you have already opened the SeaMonkey browser, 

then the SeaMonkey mail client can be opened in a flash, and 

the reverse is also true. This is very useful because website 

links in the SeaMonkey mails are opened in the SeaMonkey 

browser. Firefox is a separate application from Thunderbird 

and does not have the same advantage. For this reason, I use 

SeaMonkey instead of Thunderbird. SeaMonkey is available 

at https://www.seamonkey-project.org/.

By default, SeaMonkey looks like Firefox or Thunderbird. 

I prefer to change its appearance using the Modern theme, 

as it makes it look like the old Netscape 6, and also because 

I need the browser to look different from regular Firefox. To 

enable this theme, go to 

Tools » Add-Ons » Appearance » 

Seamonkey Modern

.

Even on a desktop screen, space may be at a premium. 

Currently, Thunderbird and SeaMonkey do not provide an 

easy way to customise the date columns. I use this trick in the 

launcher command to fix it.

export LC_TIME=en_DK.UTF-8 && seamonkey -mail

have to empty the Inbox and Trash, and also delete all archived messages.
