[QUOTE="MSMacMan, post: 1342983, member: 228573"] Hey Everyone, You all using Apple Mail or Outlook 2011? Anyway, if you cannot send mail but can receive mail, your outgoing mail server is unavailable. Easy way to test this: You provider will tell you how to connect (what servers, and what ports to use) Check to see what is currently configured, make sure it matches their site If it does, and its still not sending but IS RECEIVING... Go to terminal, and type 'telnet *Server* *Port*' So if google told me my outgoing settings are: smtp.gmail.com port 25 I would type 'telnet smtp.gmail.com 25' (without quotes) You should get a header. If it says you cannot connect, its a connectivity issue and you will have to check your firewall/ISP. If you do get a header, then you need to call your provider. A bit about how email works: For standard email, you are either connecting through IMAP4 or POP3. So your incoming mail server will be IMAP or POP3 protocol Your outgoing WILL BE DIFFERENT, and is usually SMTP. So if your IMAP or POP3 connection is working, and you can receive mail, but you cannot send mail, your SMTP outgoing server is not reachable. Let me know if you have any questions. [/QUOTE]
