Hi all; In my /etc/postfix/main.cf, I have the following entry virtual_alias_maps = hash:/etc/postfix/valias In this file, it contains this entry. @faxoutlook.company.fax mail2fax I ran "postmap" command on my Ubuntu to create valias.db hash file, however; when I tried to send a email2fax email from my Outlook. The Hylafax does not grab the fax number from email address like [email protected], instead; Hylafax grabbed "mail2fax" as destination fax number. If I changed "@faxoutlook.company.fax mail2fax" to "@faxoutlook.company.fax 6049764567", a real fax destination number, the fax can go out from HylaFAX. Suppose, the PostFix and HylaFAX would grab the fax number out from my special email address, I am not able to figure out what is my wrong configuration. Can anyone tell?
