Exchange cant retrieve external mails. RRS feed

  • Question

  • Hello,

    Am using SBS 2011 and exchange 2010.  

    initial maxmailsize set at 10mb, increased to 20mb. Through this site. Heavy mail now in the mailbox. Good + Thank You. 

    Now, i see new mails when i log into the ISP yet pop3 connector sees no new mails while trying to retrieve. Internal mails within the domain, ok. Out going mails to other domains, ok too. incoming (external)mails stop at the ISP and pop3 doesn't see them as new mails hence does not retrieve them. log pasted below.

    =======================================================
    Log opening: 09:44:02 : 08/21/12

    [t 0] 08/21/12, 09:44:02:     -- Pop3Connector --

    The "POP3 Connector" is a SBS feature. It isn't part of Exchange.
     
    However, if STAT (a POP3 command http://www.ietf.org/rfc/rfc1939.txt)
    isn't reporting any new messages then the ISP has no messages in their
    maildrop for you. You'll have to ask them why.

  • Thanks Rich,

    I have read the RFC1939 and am going back to the ISP chaps with tough questions.

    Now am reassured that the SBS isn't the issue. .........POP3 connector??? or do i just get a third party POP3 connector? Any pointers??

    (Thinking aloud here)

    Blink.


    Thank You & Best regards, Blink Lucas.

  • Hi,

    Looking around for a third party pop3 connector as we need the webmail as our redundant site.

    Any pointers?
