I have a curious error when running an ASP script that sends e-mails to our subscribers (the script is from Ocean12). There are almost 15.000 subscribers and the script worked fine until something was upgraded on the server. Now the script runs very slow (about 10x slower than before) and at a certain moment (after sending about 1/3 of mails) it gives this error and stops: Code: Persits.MailSender.4 error '800a0006' 501 Syntax error /ocean_mail/send2.asp, line 69 It can't be a syntax error, since it worked fine before for years. It can't be caused by a bad mail-address either, since I managed to send out our newsletter without any problem by splitting up the database in 10 smaller database containing 1.500 addresses each. The webmaster said that there's nothing wrong with the server's software... Then what the hell could cause this error?
