This bug may be a bit difficult to reproduce.. I have a pop3 mailbox and i can also access this mailbox via browser under the url webmail.webspace4you.ch .. its a product called 'VOPmail' The problem: 1) Login with the HTML Frontend (vopmail) 2) Now try to retrive your mails via mozilla mail (same mailbox, while you are logged in) Mozilla recives a message that it doesn't understand and it will try again, again, again.. here a telnet log: ulrich@oma:~$ telnet pop3.blinkenlights.ch 110 Trying 126.96.36.199... Connected to pop3.blinkenlights.ch. Escape character is '^]'. +OK VOPmail POP3 Server-NOTF 188.8.131.52 Ready <email@example.com> user firstname.lastname@example.org +OK email@example.com is welcome here pass blabla -ERR mailbox in use ..and 'mailbox in use' isn't understood by mozilla mail :)
Reporter: can you confirm this still happens on a modern build of mozilla?
> -ERR mailbox in use > > ..and 'mailbox in use' isn't understood by mozilla mail :) Of course. POP3 protcol only knows -ERR and +OK. The text after these codes is just informative and shouldn't be parsed. To submit further informations extended codes have been created in RFC 2449 and 3206. The problem is, that these extended codes are not mandatory and therefore not wide spread. A server that wants to be understood should send -ERR [IN-USE] mailbox in use. Mozillas newer than 2003-07-13 are aware of this code.
