A records exist, with one to ourdomain.com pointing to the hosted website server, mail.ourdomain.com pointing to our own server. What I have seen, though, is that fetchmail (still running luckily) is still retrieving mail from the remote server, though at a much smaller volume. mario_gudelj May 23, 2012 4:17 PM (in response to Casper Scholly) Hi Casper,The daily limit allowed through our SMTP is 500 emails a day and this can't be increased.

  6. The customer has Eset on their server because they wanted it.

Or how often do they send in a greylisting scenario? Before my transition: I haven’t been invited yet. For step-by-step instructions, click the links below. Anyone any ideas on how to stop this?
