How to configure Windows Mail Queue?

[eisstern]

Hi
OpenEMM is installed on a Windows XP System and the mails will use a relay. Problem: Windows doesn't use sendmail, it sends its mails directly.
But how to config the amount of simultaniously send mails? There will be be 4000 mails. To not get on a blacklist, the sending interval should be long with a small amount of mails each time.

Any ideas?

Please change property "mailgun.ini.blocksize" in file emm.properties (path: OpenEMM\webapps\core\WEB-INF\classes) to a smaller number.
