smtp responses slow when sending emails using smtp engine and proprietary program
Posted on 2011-02-18
our development team has put together a program that sends out email directly from a GUI once they put an email address in. it actually sends out 2 emails which are confirmations,one goes to the BUYER and one to the SELLER. the program apparently uses the default MAPI profile of the person that is logged into the PC to send email
we updated our exchange environment and we have a 2003 environment, as well as a 2007 environment.
when relaying email off of the 2003 environment, it works flawlessly
when relaying email off of the 2007 environment, there are some delays when sending email, and it looks to be as if it gets delayed 5 seconds, and sometimes 10 seconds if there is a lot of email traffic at once. i read up a little on tarpitting, could this be the cause of the delayed emails? anyone have any other ideas? how can i turn tarpitting off?
