The new POP3 server will refuse plain text authentication unless you are using SSL. You will need to change your mail client to select APOP or MD5 Challenge/Response and/or select port 995/SSL
pop username has to be username@domain
"firstname.lastname@example.org" not just "fred"
password is your password
authentication method is either APOP or MD5-CRAM
port is 110 or 995 (with 'use SSL' checked)
Successful setup using Thunderbird email client:
Fetchmail: (By nwrickert )
Here's my ".fetchmailrc" entry
skip dslr via mail.dslr.net proto apop
user ********@dslr.net with pass "********" ssl is ******** here
The "skip" means to not automatically use this entry. I use fetchmail dslr to specify it. Change "skip" to "poll" to have that mailbox automatically checked whenever fetchmail is run.
