Making an automatic copy of all inbound emails

*Create /etc/procmailrc PMDIR=/etc/procmail

LOGFILE=/var/log/pmlog

VERBOSE=yes # Set to yes when debugging; default is no

INCLUDERC=$PMDIR/rc.localcopy

*Create directory (files) and change permission (presume sendmail is running as root)

chmod 400 /etc/procmailrc

mkdir /etc/procmail

chmod 700 /etc/procmail

chmod 600 /etc/procmail/*

touch /var/log/pmlog

chmod 600 /var/log/pmlog

*Create /etc/procmail/rc.localcopy as follow:

:0c

! postmaster@mydomain.com # each messages will be forwarded to postmaster

Making an automatic copy of all outbound emails (tested in Redhat 8.0)

*Create /usr/share/sendmail-cf/cf/sendmail.mc (add the following line).

LOCAL_CONFIG

CP PROCMAIL

LOCAL_RULE_0

R$*$: <> $1

R<> $+ < @ $+ . PROCMAIL . >$: $>canonify $1 @ $2

R<> $+ < @ $+ . >$: <> $1 < @ $2 >

R<> $+ < @ $+ > $#procmail $@ /etc/procmail/procsh$: $1 < @ $2 . PROCMAIL . >

R<> $*$: $1

MAILER(local)dnl

MAILER(smtp)dnl

MAILER(procmail)dnl

*Replacing all with real TAB and ./Build sendmail.cf.

*cp /usr/share/sendmail-cf/cf/sendmail.cf /etc/mail/sendmail.cf

*/etc/init.d/sendmail restart

* Create /etc/procma

il/procsh as in sendmail.cf as:

PMDIR=/etc/procmail

LOGFILE=/var/log/pmlog

VERBOSE=yes

:0

* !^To:.*@yourdomain.com # for any emails sending out (not local domain)

{

:0c:

/var/mail/outbound # make a copy

}

:0

! -f "$@" # send message back to sendmail for handling

*chmod 400 /etc/procmail/procsh

* Make sure procsh is different from /etc/procmailrc because /etc/procmailrc is system level rc file for procmail. It could be used for CC inbound emails. Don't mix them together.

NOTES: By setting sendmail to use procmail as LDA (local delivery agent) in order to make a copy of all outbound emails, this sendmail server lose the ability to receive inbound emails. So far, I have not figured out how to solve this issue in sendmail. If you have any idea, please post it to this forum.

A work around is seperating inbound & outbound email servers, such as setting up an outbound email gateway (which is not uncommon), and using the standard sendmail configuration for inbound emails. Another option is using 2 sendmail binaries in this server, one for outbound and another for inbound, but it needs to be tested.

有没有关于qmail 的发进和发出邮件的备份方案？
