Author: erics, Posted October 31st, 2011 at 3:00:38pm

Here are the Amazon docs: http://docs.amazonwebservices.com/ses/latest/DeveloperGuide/index.html?IntegratingWithServer.Sendmail.html

Edit sendmail.mc and generate a new sendmail.cf

# yum install sendmail-cf mailx
# cd /etc/mail
# cp sendmail.cf sendmail.cf.original
# cp sendmail.mc sendmail.mc.original
# vi sendmail.mc - Apply edits shown below
# make -C /etc/mail
# vi mailertable
# makemap hash /etc/mail/mailertable < /etc/mail/mailertable
# service sendmail restart

# yum install sendmail-cf mailx

# cd /etc/mail

# cp sendmail.cf sendmail.cf.original

# cp sendmail.mc sendmail.mc.original

# vi sendmail.mc - Apply edits shown below

# make -C /etc/mail

# vi mailertable

# makemap hash /etc/mail/mailertable < /etc/mail/mailertable

# service sendmail restart

/etc/mail/mailertable

.{TAB}aws-email:%0

Replace the {TAB} with an actual tab character, and the last character is a zero.

/etc/mail/sendmail.mc

Change:

DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

To:

dnl DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Please note above the space after the leading ‘dnl’ and that there is a trailing ‘dnl’ as well.

Enable the following lines by removing the leading ‘dnl ‘ or add them as needed:

MASQUERADE_AS(yourDomain.com')dnl FEATURE(masquerade_envelope')dnl FEATURE(`mailertable')dnl

Add the following line, edited to match your installation:

Maws-email, P=/opt/aws/bin/ses-send-email.pl, F=mDFMuXn, U=smmsp, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP, A=/opt/aws/bin/ses-send-email.pl -r -k /root/aws_credentials -e https://email.us-east-1.amazonaws.com -f $f $u
