email problem - unique identifier


Recommended Posts

Posted

Hi, i wonder if anyone else has had similar problem when trying to receive email.

The phone says mail cant be received as your server does not provide a unique identifier for each message. Any help would be excellent.

many ISP's do not provide uidl's

a unique identifier is generated by the MTA ( mail server ) when the email arrives on it.

It normally consists of a random number plus the time of arrival plus the servers name.

these are a requirement of RFC 1939

          In order to simplify parsing, all POP3 servers are required to

          use a certain format for unique-id listings.  A unique-id

          listing consists of the message-number of the message,

          followed by a single space and the unique-id of the message.

          No information follows the unique-id in the unique-id listing.

          The unique-id of a message is an arbitrary server-determined

          string, consisting of one to 70 characters in the range 0x21

          to 0x7E, which uniquely identifies a message within a

          maildrop and which persists across sessions.  This

          persistence is required even if a session ends without

          entering the UPDATE state.  The server should never reuse an

          unique-id in a given maildrop, for as long as the entity

          using the unique-id exists.

The problem is, it is NOT implemented by many ISP's

Most email clients ( outlook express etc ) create a pseudo uidl file locally (i.e. outlook express creates pop3uidl.dbx) to work around this.

I am not aware of any PDA's or the like, that use this workaround

there are only 2 fixes.

1). Your ISP implements this functionality...

2). The developer of the email client you are using hack (proper use of the term, dont get excited..) a workaround.

well talk21.com does provide this.

outgoing server: out.talk21.com

incoming: in.talk21.com

I have an account with them from way back,however they are no longer providing NEW talk21 accounts, instead you get redirected to btopenworld, therefore i cannot provide a link for you. Although you may be able to find one through google or yahoo.
