imap_open issue

[Eric]

Hello,
I am using imap_open ("{pop.server.com:110/pop3/
notls}INBOX","user","password") in a page that gets emails with pop3
protocol.
Imap_open works perfectly on my PC + easyphp1.8, but not on a server +
Debian + php5/Apache2 + php5-imap. Error message is "Couldn't open
stream". Looking further (print_r(imap_errors())), the real error
message is "Security problem: insecure server advertised AUTH=PLAIN".
But I do not understand this message ...

I would personally look at your mail server configuration. I do not
have much experience with imap, however I used it once. My suspicion
is that if it does not work out of the box its most likely the mail
server settings.

I thought the same on the beginning. But it is working on the PC, so
it seems to be due to the Debian settings/tools. On the concerned
server, telnet on port 110 is working but not my imap_open function.
