    Hello,

    This is probably pretty straight forward, but it has me puzzled.

    I have setup an IMAP server on Exchange and it works fine within a local environment on private IP's.

    I can't seem to access the IMAP server from the outside world though. I have tried using the public IP of the mail server in the IMAP client but it doesn't seem to work.

    I also noticed that I can only assign private IP's to the server in the system manager. Is this the norm??

    Could someone point me in the right direction please!

    Muchos gracias

    Sorry, I forgot to add that I have tried using imap4.domain for the IMAP4 server name and it still doesn't connect.

    smtp.domain does seem to work though? :blink

    Have you forwarded the IMAP ports on your firewall (143 or 993 for secure imap) to the mail server?

    The firewall is managed remotely so I can't say for sure. I have tried to telnet the mail server on port 143 and the connection times out so I guess the port is closed.

    I shall have a word with the firewall dudes and check the status of the port.

    Thank you :thumbleft

    Ok, firewall port 143 has been opened. I can receive IMAP mail using the public IP of the mail server.

    I can't seem to receive email if I use imap4.domain.com as the server name though. Do I need a DNS entry for this to work?

    Cheers

    yea you will need a DNS entry to access the server by name, that's if you are trying to access the server from the internet (not intranet).

    Righty ho, I have added a DNS entry for imap4.domain.com that points to our mail server's public IP and I am now able to retrieve IMAP email from the internet. Hoorah!

    Thanks for your help AJ :thumbleft
