Ngepop Email Gmail

1. Persiapan aplikasi yg dipake:

• Install OpenSSL

# cd /usr/ports/security/openssl
# make install USE_NONDEFAULT_X11BASE=yes
# make clean USE_NONDEFAULT_X11BASE=yes

• Install fetchmail pastikan support SSL.

# cd /usr/ports/mail/fetchmail
# make install USE_NONDEFAULT_X11BASE=yes
# make clean USE_NONDEFAULT_X11BASE=yes

• Install mutt

# cd /usr/ports/mail/fetchmail
# make install USE_NONDEFAULT_X11BASE=yes
# make clean USE_NONDEFAULT_X11BASE=yes

• Install maildrop.

# cd /usr/ports/mail/maildrop
# make install USE_NONDEFAULT_X11BASE=yes
# make clean USE_NONDEFAULT_X11BASE=yes

• Install ssmtp.

# cd /usr/ports/mail/ssmtp
# make USE_NONDEFAULT_X11BASE=yes

• Modifikasi biar sedikit tampil lebih gaya:

# cd /usr/ports/mail/ssmtp/work/ssmtp-2.61
# vim ssmtp.c
...
smtp_write(sock,
"Received: by %s (sSMTP by Internet and Game PC Kumprang); %s", hostname, arpadate);
...
# make install USE_NONDEFAULT_X11BASE=yes FORCE_PKG_REGISTER=yes
# make clean USE_NONDEFAULT_X11BASE=yes

2. Pengecekan dan konfigurasi:

# openssl version
OpenSSL 0.9.7d 17 Mar 2004
# fetchmail -V
   ...
   This is fetchmail release 6.3.8+RPA+SDPS+SSL+OPIE+NLS.
   ...
   # cat /usr/local/etc/ssmtp/ssmtp.conf
   root=postmaster
   mailhub=smtp.gmail.com:465
   rewriteDomain=indofreebsd.or.id
   hostname=mx1.kumprang.com
   FromLineOverride=YES
   UseTLS=YES

3. Pembuatan hash sertifikat untuk GMAIL:

• Pertama-tama kita check gmail sertifikat terlebih dahulu:

$ openssl s_client -connect pop.gmail.com:995 -showcerts
     CONNECTED(00000003)
     depth=0 /C=US/ST=California/L=Mountain View/O=Google Inc./CN=pop.gmail.com
     verify error:num=20:unable to get local issuer certificate verify return:1
     depth=0 /C=US/ST=California/L=Mountain View/O=Google Inc./CN=pop.gmail.com
     verify error:num=27:certificate not trusted verify return:1 depth=0
     /C=US/ST=California/L=Mountain View/O=Google Inc./CN=pop.gmail.com verify
     error:num=21:unable to verify the first certificate verify return:1

• Atau biar lebih gampang download saja:    

$ fetch http://optusnet.dl.sourceforge.net/sourceforge/souptonuts/googlepop.pem
$ fetch http://optusnet.dl.sourceforge.net/sourceforge/souptonuts/equifax.pem

• Biar default $PATH bisa digunakan untuk semua user dalam 1 box lebih baik ada simpan di /usr/src/crypto/openssl/certs/.

$ su -
# cd /usr/src/crypto/openssl/certs/
# mv ~budsz/*.pem /usr/src/crypto/openssl/certs/
# chown root:wheel googlepop.pem ; chmod 644 googlepop.pem
# chown root:wheel equifax.pem ; chmod 644 equifax.pem

• Rehash atau creating symlinks:

# cd /usr/src/crypto/openssl/certs/
# c_rehash .
# ls -l | grep googlepop.pem
     lrwxr-xr-x    1 root     wheel          13 Jul  1 04:08 7f549ca4.0 -> googlepop.pem
     -rw-r--r--    1 root     wheel        1054 Jul  1 03:35 googlepop.pem
# ls -l | grep equifax.pem
     lrwxr-xr-x    1 root     wheel          11 Jul  1 04:08 594f1775.0 -> equifax.pem
     -rw-r--r--    1 root     wheel        1143 Jul  1 03:35 equifax.pem

• Kita check ulang sertifikat yg sudah kita bikin:

$ openssl s_client -connect pop.gmail.com:995 -CApath /usr/src/crypto/openssl/certs
     CONNECTED(00000003)
     depth=1 /C=US/O=Equifax/OU=Equifax Secure Certificate Authority verify return:1

4. File-file yg diperlukan $HOME, diataranya ~/.fetchmailrc:

$ cat .fetchmailrc
   poll pop.gmail.com
   proto POP3
   user budsz@indofreebsd.or.id
   password xxxxxx
   options nokeep ssl sslcertpath /usr/src/crypto/openssl/certs/ smtp smtp.gmail.com
   mda "formail -bcYzq- | /usr/local/bin/maildrop"

$ grep "set sendmail" .muttrc
   set sendmail="/home/budsz/gmail-smtp.sh"

$ cat gmail-smtp.sh
   #!/bin/sh
   /usr/local/sbin/ssmtp -au " budsz@indofreebsd.or.id " -ap "xxxxxx" $@
   $ chmod 700 gmail-smtp.sh
   $ cat .mailfilter
   PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"
   SENDMAIL="/usr/local/sbin/ssmtp"
   SHELL="/bin/sh"
   VERBOSE="0"
   LOGNAME="$HOME/Mail/Log"
   LOG="$HOME/Mail/log"
   DEFAULT="$HOME/Mail/Inbox"
   MAILDIR="$HOME/Mail"

   `reformail -D 8000 duplicate.cache`
   if ( $RETURNCODE ==0 )
   exit

• Silakan isikan filter mail selengkapnya, kita test nge-pop skg:

$ fetchmail -va -f ~/.fetchmailrc
