question

Wonder if someone can advise. One of our 3rd party applications is using database mail for mail shots and recently added the ability to have attachments. I first realised this was happening when msdb grew about 10 times faster than usual and the server virtually stopped. The application was sending over 6k mails with attachments. I had to clear out the log files to get everything working again and banned the use of attachments as this was a new feature in the application and they had lived without it. Does anyone have any experience of working with dbmail in this way because I didn't think that was what dbmail was designed for. Thank you.
