Wednesday morning, patches were applied to the operating system of the campus e-mail server machines. These patches were recommended by the vendor, Sun Microsystems, to fix some security related problems. We later discovered that the patches have an undesirable side effect on the way POP and IMAP based e-mail clients (e.g., Z-Mail for Windows, PC Pine, Eudora, Pagasus) verify passwords. This resulted in an error message, "ERR Bad Login", when these e-mail clients tried to connect to the servers. We've removed the patches and are working with the vendor to ensure that they can be applied again without impacting our e-mail client programs. We regret the disruption this caused. *** Note *** Only those POP and IMAP e-mail clients incorrectly configured to connect to "<userid>.mail.yorku.ca" were affected. If you are using a POP or IMAP based e-mail program, ensure it's configured to use "postoffice.yorku.ca" for POP or IMAP services. Contact CCS Help Services if you are uncertain or need assistance. -- Marshal Linfoot Phone: (416) 736-5257 x22691 Manager, UNIX Technical Support FAX: (416) 736-5701 CCS, York University E-mail: [log in to unmask]
