Mail-to-Fax

Preparation

Setup your mail server so that all e-mails are forwarded to your pascom server via the domain .fax per SMTP.

On your mail server, setup an inbox which can be retrieved via either POP3 or IMAP by the pascom phone system.

Example:
fax@mydomain.com

Configuration

In order to be able to use Mail-to-Fax, you will need to setup your virtual fax server using the following pascom phone system admin UI menu options: Appliance > Services > Fax Server.

Under Mail to Fax you can choose, whether the content of the e-mail or only the attachment should be faxed.

Regardless of which option you choose, further configuration fields regarding your pre-prepared e-mail inbox will appear.

Setting	Description
Mail Server	Enter the mail server on which the prepared inbox is located.
Mail Protocol	Enter whether the E-mails should be retrieved using POP3 or IMAP (Default setting).
Retrieval interval	Only for POP3 accounts: Enter the time interval in seconds at which e-mails should be retreived.
Remove from mailbox	Enter whether the e-mails should be removed from the inbox once retrieved or whether they should continue to be saved. Default: Yes
Mail Username	Enter the username for your pre-prepared inbox
Mail Password	Enter the login password for your preprepared inbox
Ignore invalid certificates	Enter whether or not your pascom phone system should ignore invalid certificates. Default: No

Check to make sure that your pascom phone system can correctly connect to your mail server inbox.

Sending Faxes

Once the setup has been completed, to send a fax simply send an e-mail with the following construction:

Field	Example	Description
To	fax@mydomain.com	Enter the e-mail address of your pre-prepared inbox.
Subject	00991123456999	Enter the to be used trunk prefix + the fax number of the recipient.
Attachment		This is the actual fax as PDF or TIF file.

Depending on your fax server configuration choices, the contents of the e-mail will also be sent in the fax.

Customisations

Currently, it is only partially possible to customise the behaviour of the Mail-to-Fax gateway and must be done directly in the configuration file. To this end, you will need to log into your pascom phone system via SSH and will require Root permissions.

Without any customisation, the default setting is to send out a plain-text e-mail whenever there is a change in a fax job (busy, failed, successful, etc.).

This setting can be changed to use an alternative format. As such, this generates an HTML e-mail with an embedded first page and PDF attachment. The fax itself will be sent as an attachment in PDF format. This format is the same as the one used when a fax is received by a virtual fax machine configured to use the format=“inlinegif” option.

• open the file /etc/hylafax/FaxNotify in a text editor
• remove the “#” comment in the line INLINE=true
• restart in the fax system using the web interface or the _ /etc/init.d/hylafax restart _ command

Print-to-Fax

The Print-to-Fax Gateway can be used to automatically send documents from, for example, ERP systems as well as for sending documents manually using the desktop client.
