Nope, still slow even after upping the speed. I keep seeing this in the log file
10-08-2013 17:32:29 - DEBUG - 41535672 - hook_newsletter> Emails found in sending status: 1
10-08-2013 17:32:29 - DEBUG - 41536008 - hook_newsletter> Sending email 4
10-08-2013 17:32:29 - DEBUG - 42159568 - limits_exceeded> Setting the limits for the first time
10-08-2013 17:32:29 - DEBUG - 42159616 - limits_exceeded> Max number of emails can send: 56
Every time, not just the first time. Can I forward you the full log to have a look at? It contains peoples e-mail addresses so obviously I don’t want to post it here.
