EqualLogic and Exchange 2010
We have had some problems with our EqualLogics (no surprise there) doing the most simple of thing, emailing through our exchange 2010 relay. 2003 worked fine, however 2010 seems to cause a number of problems. Small notification emails are fine, however, when it comes to the diagnostics emails with their vast 2-5MB attachments something chokes and we get a time out error at the EqualLogics end, something like 'diag' or 'update' was unable to send output using e-mail. SMTP returned the following error: TimeOut] Some Googling suggests that it is either the Tarpitting Microsoft have stuck in that creates a 5 second delay to proceedings for security, or something a bit more deeper in the SMTP protocol on the receive connector on the CAS\Hub server, namely chunking and binary mime settings and it is all related to BDAT. By default the Tarpitting is set to 5 seconds, some folks have found that setting this to 0 or turning it off works for them, it didn't for me, nei
