Bidaltzailea edo hartzaileak:

The sender's email address or the name of the sender or the recipients of the message.
Gaia:

Mezuaren gaia.
Goiburu espezifikoa:

Any header including custom ones.

If a message uses a header more than once, Evolution pays attention only to the first instance, even if the message defines the header differently the second time. For example, if a message declares the Resent-From: header as "engineering@example.com" and then restates it as "marketing@example.com", Evolution filters as though the second declaration did not occur. To filter on messages that use headers multiple times, use a regular expression.
Mezuaren gorputza:

Mezuaren barruko testuan bilatzen du.
Adierazpena:

(For programmers only) Match a message according to an expression you write in the Scheme language used to define filters in Evolution.
Free Form Expression:

(For advanced users only) Combine numerous conditions by using a special syntax.
Date sent:

Filters messages according to the date on which they were sent. First, choose the conditions you want a message to meet, such as before a given date or after a given date. Then choose the time. The filter compares the message's time stamp to the system clock when the filter is run, or to a specific time and date you choose from a calendar. You can also have it look for a message within a range of time relative to the filter, such as two to four days ago.
Date received:

Bidaltze-dataren antzera funtzionatzen du, baina mezua hartu zenuen eguna eta ordua konparatzen ditu zuk zehaztutako balioekin.
Etiketa:

Messages can have labels of Important, Work, Personal, To Do, or Later. You can set labels with other filters or manually.
Puntuazioa:

Mezuaren puntuazioan 0 baino handiagoak diren zenbakiak jartzen ditu. Iragazki bat jarri edo mezu-puntuazioa alda dezakezu, eta, ondoren, beste iragazki bat jarri, puntuazioa eman diezun mezuak lekuz aldatzeko. Mezuen puntuazioak ez du oinarri zehatzik: iragazkiek prozesatu ahal izan ditzaten mezuei ematen zaien zenbaki bat da.

Jarraipena:

Checks whether the message is flagged for follow-up or completed (after a certain date).
Eranskinak:

Checks whether there is an attachment for the email.
Posta-zerrenda:

Filters based on the mailing list the message came from. This filter checks for a variety of common mailing list related headers but might miss messages from some list servers if they use uncommon headers.
Adierazpen erregularra:

(For advanced users) If you know your way around a regex, or regular expression, this option allows you to search for complex patterns of letters, so that you can find, for example, all words that start with "a" and end with "m", and are between six and fifteen letters long, or all messages that declare a particular header twice. Evolution supports the Extended Regular Expression syntax (ERE).
Iturburu-kontua:

Mezuak zein zerbitzaritatik hartu dituzun aztertzen du iragazkiak. Oso erabilgarria da, POP posta-kontu bat baino gehiago erabiltzen badituzu.

Evolution can use an external command to process a message, then process it based on the return value. Commands used in this way must return an integer. This is most commonly used to add an external junk mail filter.
Mezu baztergarrien proba:

Filters based on the results of the junk mail test.
Match All:

Applies an action always to any message, without further conditions. This could be useful at the end of the list of message filters to cover those emails that did not match any conditions for the preceding filters in the list.
