Problem in accessing mail account via cyrus pop3
 
Hi,
I am using cyrus pop3 on linux machine.
I have a useraccount on linux.
now i want to access mailbox of this user via
telnet.i am providing user and pass, but it is
accepting user but when i give pass it is not accepting
pass. i am entering correct pass (password of user), Why
this is happening, if any body have some idea please respond as early as possible.

thanks and with regards

"via telnet" is ambiguous, but bad in either way.

One somewhat obvious interpretation is that you're using telnet to log in to the machine storing your mail. Unless you know why telnet is insecure in the general case, how ssh deals with it, and why you don't need ssh, I'd advise you to switch from telnet to ssh RIGHT NOW! And besides from that, I don't know about your problem.

On the other hand, if you're using telnet to talk directly to the mail server, you really should use netcat instead--telnet inserts extra characters (at least that's what I infer from my observations--I haven't done the "use the source, Luke" part). It mostly does so when closing the connection, but... don't trust telnet to have a one-to-one correspondence between input characters and sent characters--trust netcat to be that.

So, if you're talking to the mail server directly, which authentication method are you using? Note that a "user account on linux" isn't necessarily the same as a user account to access mail. It may be the case that it is w. cyrus (I don't know), but don't just assume that it is. Look into that. Make sure the credentials are identical.

Hi Jonas,

Ermm... I still don't understand what's going on. Read "Smart Questions" by ESR (google for it), and "how to report bugs effectively" by Simon Tatham (linked to in "Smart Questions").

How many computers are involved? On which one do you run the telnet client? Which program(s) does it talk to? Which program talks to the pop3 daemon? Which set of credentials (username, password) are you using--the one for logging in (i.e. shell access)? Are you sure those are the same as for accessing your mail? How does the pop3 daemon do authentication (which authentication method)? Please post the configuration files for cyrus, or (if they're too big) a link to them. Does your setup involve any machines you don't control?

Just something to get you started --Jonas
