When we added our email account in SMTP server of bulk emailer admin settings, it crashed our email account.

For example:
My work e-mail and all of my colleagues at email are not receiving the newsletter. This is an issue that needs to be fixed.
Also, for every person on the newsletter subscriber list, we get a delivery notification called ' delivery failure' but we now that the people are receiving the e-mails. This is really annoying to have on our e-mail account. Why does this happen?
Also, how many hours does it take for the newsletter to be sent out to the whole subscriber list?

Please let us know how to fix this SMTP issue.

we are using the same authentication details as dnn site.so, why should it work on dnn and not the bulkemailer module. when we use any mail id in bulk emailer module, first time it is working fine, it is getting corrupted after some time.
