Triton - yes your ISP is blocking emails sent from us. Here is a log entry for one that was attempted to be sent to you today (with your email address asterisked out):
Apr 23 09:03:02 turbodieselregister sendmail[4852]: l3ND2olW004850: to=<***@maitlandelectric.com>, ctladdr=<webmaster@turbodieselregister.com> (1007/1007), delay=00:00:12, xdelay=00:00:01, mailer=esmtp, pri=121761, relay=smtp. secureserver.net. [64. 202. 166. 11], dsn=5. 1. 3, stat=User unknown
Contact your ISP with that info and they should be able to help you. Their SPAM blocker is probably the problem and for some reason has our notifications marked as spam and is therefore rejecting it.
As to your sent PM's by default sent PM's are not saved. When you send a PM there is a check box near the bottom that says "Save a copy of this message in your Sent Items folder. " - check that box and a copy will be saved. We did this because most users wouldn't clear out their sent box and then their box would be full and couldn't receive new PM's. We'd answer tons of support questions every day for why they couldn't receive PM's. Since making this change someone asks about once a month about why their sent PM's aren't saved. BTW, answers to many things like this are in the TDR Website/roundtable FAQ forum like this:
I have sent several private messages, but I cannot find any record of them being sent
