Hi folks, I'm running the debian package of cyrus in lenny, 2.2.13-14, and I've encountered some odd behaviour with Mac Mail that I'm struggling to explain. Emails that have been successfully delivered sometimes fail to appear in Mac Mail clients for many hours. I'm currently uncertain if it's being caused by cyrus or Mail.app, although it has only started happening since we moved from a compiled 2.2.12 version to the debian package on new hardware - we migrated the mailboxes using the cyradm 'xfer' feature. Exim's mail logs report successful delivery, and the timestamp of the file in the cyrus spool matches the delivery time. If checked with another email client, such as squirrelmail, the emails are in the mailbox. I'll mention that our squirrelmail installation connects using imap through a perdition proxy, just for completeness, but there are some users who have experienced this delay without using any other email clients. Using the example of one of our sysadmins yesterday, an email was delivered into his mailbox at 10:09. It appeared in Mac Mail at approximately 4pm. In the intervening hours, other messages were delivered and appeared in Mac Mail; I also see several successful logins from his mac to the imap server, regular opening of "INBOX.Apple Mail To Do" and so forth. During that time he had no other email client open. I also checked and found that Mac Mail was configured to use the 'IDLE' command, which, when manually testing it, appears to be working satisfactorily. Has anyone encountered something like this before?
