Mail server setup question: remote client's can't connect
I'm new to Linux mail server configuration, so sorry if this is a dumb question:
I've just set up my Linux box as a mail server for my various domains. I seem to have my MX records, sendmail, etc. set up properly, as I can send and receive mail fine when logged in to the box (via emacs -RMAIL). However I can't seem to connect to the server remotely from any email clients (Thunderbird, Outlook, etc.). The mail client times out when trying to check mail.
When trying to connect remotely, I'm using my Linux account credentials, as I'm expecting my remote mail client to use the same mailbox as I use when logged in locally and using emacs to send/receive. Do I misunderstand something?
Thanks in advance for any help or suggestions!
tried both, but using IMAP
Thanks for the reply. I've tried both, but my preference is IMAP.
