Project Description:
Hello Freelancers,

I'm currently running interspire email marketer 6.1.0 (IEM)
and using amazon SES as my smtp relay service.
right now IEM is installed on a hostgator shared baby account.

i have realized that my emails are going into the gmail spam box.

so i need help with the following items
-- figuring out why my emails are going into the gmail spam box
-- modifying IEM to sign emails with DKIM
-- setting up DKIM and any other related DNS settings to ensure maximum deliverability

The other big thing I need help with is speeding up the sending rate of IEM
right now it takes about 10 hours to send out to a list of 45,000
i understand this is due to IEM making only one connection at a time to amazon SES.

I would like someone with experience to modify IEM to be make multiple connections (multi thread) and therefore
send out faster.

thanks for reviewing my job posting.
