Hi all. I have a phpBB forum setup which has around 900+ members. I try to use the mass email feature to email all of the members, however, only a handful actually receive the email (maybe around 10). I can see the email in the mail queue using the Plesk Control Panel. After a while, it disappears from the queue, and I receive the following email: ======= Hi. This is the qmail-send program at mail.myserver.com. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <firstname.lastname@example.org>: Unable to run qmail-remote. (lots of the members email addresses with the same error as above) ======= The mass email feature has worked before when there wasn't as many members on the forum. However, now that more people have registered, the emails never get sent out and I've no way of contacting the forum members. Is there a limit to the number of recipients an email can have? Could that be causing the problem? Any help would be much appreciated, as MediaTemple (my server hosts) aren't helping at all. Thanks David.
