sbs 2011 is the dc. i use exchange pop3 for my incoming at outgoing emails. www.kinesphere.com
. the smarthost was never setup since exchange pop3 handles it inhouse. initially a hosting company "abc.cm" was hosting my web page and emails hence my smtp was configured as "mail.abc.com".all was good until recently have switched to another hosting company called xyz.com . the outgoing server in exchange pop 3 was changed to "mail.xyz.com". now i cant send outgoing emails. have checked with xyz and have confirmed the smtp is coorect. issue is never mind the outgoing the email address im using to authenticate the smtp server will not authenticate. i figured i should try the isp's "cabblecompany.com" smtp and that will not authenticate either. hope im not confusing you folks wiith my post . any help will be appreciated. thanks in advance.
