SMTP Service Fails with BusinessWorks 2018

SUGGESTED

Hello,

I just installed a clean copy of BW2018 + SP 2 on a Windows 2008 Server which was used for email and IBM Lotus Domino servers.  For some reason, BW2018 seems to be interfering with the SMTP service.  Our email server stopped working.  I uninstalled BW2018 and the email server (MailEnable) started working again!  Has anyone come across this issue before?  Any idea why BW/Pervasive would interfere with an SMTP service?  Thank you.
