I used a mailing list software added to the Joomla system and sent newsletters out using SMTP in that software, but the limit was set to 100 per minute in the software (this is before I read the 500per hr message). One list had 1800 email on it. This list was sent partially good but a lot were unformatted with links, images & html formatting missing (it was not a plain text & html sending issue). Would this formatting error occur because of the throttling used with dreamhost or would the emails simply be backed up until sent. There were 1800 newsletters sent out looking very unprofessional and I don't want it to happen again so I am trying to track down the problem.
