[hylafax-users] Faxmailing through external SMTP server (plus one suggestion)

[Marcos Lorenzo de Santiago <marcos.lorenzo@xxxxxxxxxxxxxxx>]

Hi everyone,

I'd like to share a workaround for sending faxmails through an external SMTP server, via
the program nail (heirloom-mailx), which allows files to be attached at command-line options
and sent through external SMTP server. As I saw, there's been some questions about this on the
mailing-list. I hope this helps.

I needed this feature at my job and looking at the code seemed easy to implement. Also I needed
a shell-script for processing the body of the mail and attach the file as nail program wants:

<nailscript.sh>
#!/bin/sh

# Process STDIN to extract attachment filename and call nail with -S smtp=external_server_ip -a attachment_file
MAIL=""
TIFF2PDF="/var/spool/hylafax/bin/tiff2pdf"    # tiff2pdf executable
HYLAFAX="/var/spool/hylafax"                     # hylafax home
SMTP=10.5.22.6                                          # your smtp server

while read line; do
   MAIL="$MAIL$line\n"
done
MAIL=$(echo $MAIL | sed -e "s/\\\n$//" )       # remove last newline
filename=$HYLAFAX/$(echo -e $MAIL | grep tif | cut -d ' ' -f1) # get full path to the attachment
pdf="/tmp/$(basename $filename).pdf"      # the filename of the converted fax to pdf

$TIFF2PDF -o $pdf $filename && \
echo -e "$MAIL" | /usr/bin/nail -t -S smtp=$SMTP -a $pdf && \
rm -fr $pdf                                                     # remove the pdf, leave the tif file.
</nailscript.sh>

I basically removed all inline attachment and processed then after by nail. I forced mimeEncode to be ran
so that the output is just a simple "cat" of the body of the mail as nail reads it plain from STDOUT.

Also I noticed that some times the faxes has no sender in its faxinfo output:

interno1:~# faxinfo /var/spool/hylafax/recvq/fax000000038.tif 
/var/spool/hylafax/recvq/fax000000038.tif:
    Sender: 
     Pages: 1
   Quality: Normal
      Page: default
  Received: 2010:07:28 09:33:13
TimeToRecv: 0:20
SignalRate: 14400 bit/s
DataFormat: 1-D MH
ErrCorrect: No
   CallID1: 0914328098
   CallID2: 80869

Is it possible that Sender may be CallID1?? I made some checks:

interno1:~# for i in /var/spool/hylafax/recvq/* ; do callid1=$(faxinfo $i | grep CallID1: | cut -d ':' -f2 | tr -d ' ' | tr -d '\n') ; sender=$(faxinfo $i | grep Sender: | cut -d':' -f2 | tr -d '\n' | tr -d ' ') ; if [ -n "$callid1" ] && [ "$callid1" == "0$sender" ]; then echo "$callid1==0$sender OK" ; elif [ 0$sender != 0 ]; then echo "$callid1==0$sender ERR" ; fi; done

Maybe we could add in bin/faxrcvd:

SENDER=${SENDER:-$CALLID1}
