# Why do I send emails how I sent them
|
|||
|
|
|
|||
|
|
## OpenPGP signing
|
|||
|
|
|
|||
|
|
I sign my emails using [GnuPG] which is free implementation of the [OpenPGP] standard.
|
|||
|
|
The signature can be used to verify that I am the sender and that nobody modified the
|
|||
|
|
message.
|
|||
|
|
|
|||
|
|
## UTF-8
|
|||
|
|
|
|||
|
|
I use UTF-8, because it allows all characters and it's widely used everywhere. It is
|
|||
|
|
also the default character set of [Python 3]. UTF-8 is also recommended on most of
|
|||
|
|
IRC channels and networks.
|
|||
|
|
|
|||
|
|
## Plain text emails
|
|||
|
|
|
|||
|
|
I think that HTML emails only waste space. The content is HTML and even if it's not
|
|||
|
|
directly visible to the user, it has a lot of content when reading the email source.
|
|||
|
|
With plain text emails the source is only text, nothing is in HTML.
|
|||
|
|
|
|||
|
|
## Replying below quotes.
|
|||
|
|
|
|||
|
|
Many mailing lists wish emails to be replied under the quoted text and inside the
|
|||
|
|
message. It also makes the email easier to read when you know what has been said
|
|||
|
|
previously.
|
|||
|
|
|
|||
|
|
## Issues which you might have with my emails and how to fix them
|
|||
|
|
|
|||
|
|
### OpenPGP signature
|
|||
|
|
|
|||
|
|
#### Long mess as signature
|
|||
|
|
|
|||
|
|
The "long mess" should be hidden automatically by email client when you import my
|
|||
|
|
public key (I will tell you more about that later). If your email client doesn't do
|
|||
|
|
this, I suggest you to file a bug report to your email client or change it. I use and
|
|||
|
|
recommend [Thunderbird] with [Enigmail] plugin.
|
|||
|
|
|
|||
|
|
#### Importing public keys automatically
|
|||
|
|
|
|||
|
|
This will hide most of them and show you small notification about the email being
|
|||
|
|
signed. There are two ways to import keys automatically.
|
|||
|
|
|
|||
|
|
##### Enigmail level (Enigmail only)
|
|||
|
|
|
|||
|
|
Go to OpenPGP --> Settings and click "Show Expert Settings". Then open tab "Keyserver"
|
|||
|
|
and enter the following to the below box:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
pool.sks-keyservers.net
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Then click "OK" and you should get all keys automatically from pool.sks-keyservers.net
|
|||
|
|
when you receive email signed with unknown key presuming that the key is at the
|
|||
|
|
keyserver. If it's not, you will see the signature and error about key not found.
|
|||
|
|
|
|||
|
|
##### GnuPG level
|
|||
|
|
|
|||
|
|
Modify the Enigmail configuration file which should be on one of these locations:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
Linux: ~/.gnupg/gpg.conf
|
|||
|
|
Mac OS X: ~/.gnupg/gpg.conf
|
|||
|
|
Windows: C:\Users\User\AppData\Roaming\gnupg\gpg.conf
|
|||
|
|
(I'm not fully sure about Windows location)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
and add these lines:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
keyserver pool.sks-keyservers.net
|
|||
|
|
auto-key-locate keyserver
|
|||
|
|
keyserver-options auto-key-retrieve no-include-revoked import-clean
|
|||
|
|
import-options import-clean
|
|||
|
|
export-options export-clean
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You actually need only the first and third lines, but I recommend all what I mentioned
|
|||
|
|
and I explain what they do.
|
|||
|
|
|
|||
|
|
> keyserver pool.sks-keyservers.net
|
|||
|
|
|
|||
|
|
Sets the default keyserver as pool.sks-keyservers.net.
|
|||
|
|
|
|||
|
|
> auto-key-locate keyserver
|
|||
|
|
|
|||
|
|
If you are sending encrypted email to someone whose key you don't have, GPG
|
|||
|
|
tries to find it from keyserver automatically.
|
|||
|
|
|
|||
|
|
> keyserver-options auto-key-retrieve no-include-revoked import-clean
|
|||
|
|
|
|||
|
|
When doing something with keyserver, get key automatically if it's missing and it has
|
|||
|
|
signed something and the signature is being verified and when searching, do not show
|
|||
|
|
revoked keys and remove useless signatures (=signature from missing key) from keys.
|
|||
|
|
|
|||
|
|
> import-options import-clean
|
|||
|
|
|
|||
|
|
> export-options export-clean
|
|||
|
|
|
|||
|
|
When importing/exporting keys, remove all signatures that are from keys that aren't
|
|||
|
|
in keyring.
