email using SNDDST does not go to HotMail accounts

["John Allen" <jallen@xxxxxxxxxxx>]

I just noticed that using SNDDST to email reports (couple of pages) as PDF
attachment do not all get delivered to HotMail accounts.

I emailed 6 different 1 page reports to a HotMail account (individual SNDDST
used for each report) and only the 2nd and 6th one are delivered.

I tried different number of reports and all reports are never delivered, but
at least one is delivered.

 

I can email these reports to any other email accounts.

 

I am thinking it may have to do with some type of Spam Filtering HotMail
does.

 

Has anyone experienced problems using SNDDST to HotMail email accounts?
