If you think about it, this is why the IMAP standard exists - it supports multiple simultaneous logins.
POP3 is a very basic and simply protocol and really has no way of handling the concept of concurrency for a single account/mailbox. You would need, and the very least, a transaction concept that could be "shared". IMAP on the other hand is designed with this in mind. Most ISPs, at least in my experience, use IMAP for Webmail interface which in an odd sort of way gets you what you are looking for. That said, initiating an IMAP and POP3 session at the same time on the same mailbox can have rather unpredictable consequences :) Shawn -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Harald Schneider Sent: Wednesday, August 01, 2007 7:53 AM To: xmail@xmailserver.org Subject: [xmail] Re: Feature Request: Multiple POP logins Tracy wrote: > As I understand it, the POP3 specification indicates that the mailbox > will be locked for the duration of any login session.

IMHO this should be a configurable option, so that the user is aware that this only makes sense when messages are not polled by 2 or more clients in parallel. In fact many ISPs seem to skip this part of RFC1939 on their POP servers in order to offer e.g. webmail to their clients for mobile access while Outlook is still running 24h in their office. The RFC doc does not care about the common client feature to leave mails several days on the server, which makes this restricion outdated. If concurrent logins are handled on properly server level, it won't cause much trouble on client side ... -- Harald > > If you need multiple login access to a mailbox, you really need to move > to IMAP (which, as I understand it, is under development - or there are > third-party solutions which can be deployed with xmail). > > Harald Schneider wrote: >> Hi, >> >> currently a POP box is locked for further logins which is a problem when >> trying to access the box from other clients or via webmail in parallel. >> >> Now we have the feature to keep mails on pop3linked boxes which screams >> for that feature too.
