Re: We have some questions about James ?

1. I'd have to check, but I'm pretty sure that the headers of an email message are required to be 7-bit data. I was just reading through the JavaMail API last night that said something about this, and someone using the API needs to properly encode data when setting headers.

2. There is no way to change the admin passwords without restarting James. However, changes to user accounts don't require a restart.

Subject: We have some questions about James ?

Dear sir/madam,

I'm yongam, Kang from CyberCell Korea Co.Ltd. We, CyberCell, is Web solution provider company in Seoul, Korea. We are planning to use "James" for our new products, which is due out soon. However, we've come across some unexpected problems. With regard to "James", we have some questions as follows:

1.The James from mail client(Web mail) in mail header information(subject) cannot encode 2-byte character like Korean when we receive mails. Could you please explain to us why it keeps on happening?

One more question, would you please let us know what is the source code in connection with this problem so that we can come up with some solutions to these problems our ourselves?

2. When mail server is in operation, is there any way for us to change passwords without restart mail Server?

As I mentioned earlier, we are in the final stage of developing new products. However, we cannot
proceed our work due to these problems. As a matter of fact, it is kind of urgent.
Thank you in advance for your help. We would greatly appreicate it.
We'll look forward to hearing from you soon.

Sincerly,

Yongam, Kang

Hi. It's my first posting....

I heard Mr. Kang is in a hurry.
If You Want to update ADMIN PASSWORD dynamically...
You can Change Source Code of RemoteManager.java
Just Change checking block into what you want to do...

It's very happy to find other developer using JAMES in Korea...
If You Have any question
you can send me e-mails in KOREAN.

I agree completely about 8BIT ESMTP commands and how messages can have 8bit
data.  But, this is 8-bit MIME content, not headers.

Check RFC 2047 (MIME Part Three: Message Header Extensions for Non-ASCII
Text), page 2:

"A mail composer that implements this specification will provide a means of
inputting non-ASCII text in header fields, but will translate these fields
(or appropriate portions of these fields) into encoded-words before
inserting them into the message header."

"will" is the strongest statement RFCs make, so to comply with this spec,
you cannot put non-ASCII text in a message header.  This is the RFC that the
JavaMail API references when it says it does not handle the encoding for
you.  Maybe there's a newer RFC that relaxes this restriction...

It really depends on mail server and the features that it supports. If the 
mail server's greeting contains ESTMP and the necessary extention (I think it 
is called 8BIT ?????) then clients will transmit 8-bit encoded messages. If 
the receiver does not support 8-bit then it is up to sender to transform it 
into 7-bit.

A while ago one of my mail relays was only 7-bit clean and thus I always had 
my mail converted to look like what you have. (It also added a header saying 
something like converted to 7 bit on node foo at time X).

Now my mail comes through only 8-bit servers so looks fine ;)

Cheers,

Pete

If you have MIME, why should you debate on 7 or 8 bit?
I believe that MIME messages are alway 7 bit; that's the purpose of the
encoding, right?

I think 8 bit messages are not good; not all terminals can display them
correctly. On a gnome-terminal using pine, here in my place, the name has
a representation of "top-right" character between the "R" and "n".

I'm not so sure the entire DATA part can by 8-bit... maybe this is just my
James server screwing with things, but this is what Mr. Rønning's From
header looked like...

I am fairly sure the whole DATA message part can be 8bit *if* the appropriate 
extention is used. However the rest of data stream must be 7-bit. Talking 
from experience because I managed to crash a bunch of servers when sending 
high bytes in commands ;)

Pete

ESTMP may be 8 bit. See if my surname goes through...
