Using the Enigmail Rules Editor: Edit OpenPGP Rule

In the Rules Editor, you can specify defaults per recipient for enabling encryption, signing and PGP/MIME, and to define what OpenPGP key(s) to use. In this dialog, you can specify the rules for a single recipient, and for a group of recipients with very similar attributes.

Set OpenPGP Rules for
Contains the email addresses of the recipients (without names, i.e. just an address like somebody@email.domain). You can specify several email addresses, separated by spaces. The address specified here can consist of only the domain section so that mail to any address at that domain will be matched, e.g. @email.domain will allow matching to body@email.domain, somebody@email.domain, anybody@email.domain, etc.
Apply rule if recipient ...
This modifies the matching of the email addresses. If multiple addresses are entered, the setting will apply to all. The examples below are based on body@email.domain entered in the OpenPGP Rules field above.
Continue with the next rule for the matching address
Enabling this function will allow you to define a rule but not have to specify a KeyID in the Use the following OpenPGP keys: field, so that the email address is used to check for a key at the time of sending. Also, further rules for the same address(es) will be processed as well.
Do not check further rules for the matching address
Enabling this function stops processing any other rules for the matching address(es) if this rule is matched; i.e. rule processing continues with the next recipient.
Use the following OpenPGP keys:
Use the Select Key(s).. button to select the recipient keys to be used for encryption. As in the action above, no further rules for the matching address(es) are processed.
Default for Signing
Enable or disable message signing. This either uses or overrides what you have specified in the message composition window. The values are: These signing settings are applied for all rules that match. If one of the rules disables signing, the message will not be signed, regardless of other rules that specify Always.
Encryption
Enable or disable message encryption. The allowed settings and their meaning are the same as for message signing.
PGP/MIME
Enable or disable the use of the PGP/MIME (RFC 3156) message encoding. If PGP/MIME is disabled, the messages are encoded using "inline PGP". The allowed values and their meaning are the same as for message signing.

The rules are processed in the order displayed in the list in the OpenPGP Rules Editor. Whenever a rule matches a recipient and contains a OpenPGP Key ID, in addition to using the specified Key ID, the recipient is not considered anymore when processing further rules.
