[Zope-dev] zope's ESMTP support

hi all, I want to make our Zope 2.7 based site support ESMTP MailHost. And I found 2 resource: 1. "ESMTP MailHost":http://zope.org/Members/bowerymarc/ESMTPMailHost. After a simple test, I found the product is likely not compatible with Zope 2.7. 2. cvs head of zope's default MailHost product. The cvs log said it supports ESMTP now. And now I am more interested in the 2nd product. What is the status? compatible with zope 2.7? stable to use? (It doesn't work with my zope2.7 too :-( ) Could anyone give me any info? -- panjunyong
