DESCRIPTION¶
The courierfax module (if enabled by the system administrator) sends E-mail messages by fax. Addressing an E-mail message to the address 5558888@fax faxes a printed copy of the message to the specified phone number. The ability to send faxes may be restricted, or not available. The E-mail message may be a MIME-formatted message. All attachments are concatenated and sent together in a single fax transmission. courierfax only knows how to handle certain kinds of attached. Obviously, trying to fax a voice .mp3 attaching is not going to work. courierfax knows how to handle plain text, Postscript, and PDF MIME attachments. courierfax might also know what to do with other kinds of attachment, depending on some optional software installed by the system administrator. courierfax may also be able to read GIF, PNG, and JPEG images.Send a low-resolution fax.
-ignore
Ignore any attachment types that courierfax
doesn´t understand.
-cover
Send a cover page only. This is useful in
limited situations, with something like this in a
dot-courier(5)[1] file:
This .courier file faxes the contents of a message, sans any attachments,
immediately upon receipt in addition to saving the message in the
mailbox.
./Maildir ! 5552222@fax-cover
FAX TRANSMISSION RECEIPT¶
The sender will receive a fax transmission receipt if the sender requests an ESMTP delivery status notification. This is the -N option to sendmail(8)[2]:sendmail -Nsuccess 5556666@fax <messagefile
ADDITIONAL DIALING OPTIONS¶
Most faxmodems pause and wait for a secondary
dialtone, before dialing the rest of the number.
-
The dash is replaced by a comma in the dialing
string. A comma results in most faxmodems pausing for two or three seconds
before dialing the rest of the number. It is not possible to enter a comma
directly, because commas are used to separate multiple E-mail addresses. Use
dashes instead of commas in the dialing string. courierfax replaces all dashes
with commas before dialing the faxmodem.
+
Similarly, courierfax replaces all pluses with
“@” characters before dialing. An “@” characters
results in most faxmodems waiting for the line to be silent for five seconds
before dialing the rest of the number. It is not possible to enter a
“@” directly as part of the telephone number itself, for the
obvious reasons. Use pluses instead of “@”s in the dialing string.
courierfax replaces all pluses with “@” before dialing the
faxmodem.
CONFIGURATION¶
The slightly arcane configuration file, /etc/courier/faxrc, sets up which dialing strings are valid. The default configuration file contains judicious comments that explain all the parameters, and what they do. The default configuration file disables courierfax by rejecting all telephone numbers. The file must be edited in accordance with the embedded instructions, in order to enable faxing. Using webadmin is highly recommended. Upon demand, webadmin will install a suitable configuration file for the North American numbering plan, that receives all telephone numbers as ten-digit numbers, and adds any required long distance prefix, or removes the local area code, as appropriate. Or, webadmin will install a bare-bones configuration file that dials any requested phone number, without any editing or transformation.BUGS¶
There is no good way to sleep until a modem lock is released, so we poll every minute.SEE ALSO¶
