Use of the php IMAP functions on BSDi webserver with Apache against a cyrus server on BSDi 4.2 will eventually cause the mail server to hang, forcing a hard reboot. A BSDi 4.2 Cyrus server could be remotely DOS'd if external IMAP access is available. This has been experienced running IMP and Jawmail, two popular OSS webmail packages which do not exhibit this behavior on other platforms. This has been tested with the php compiled against c-client versions 2000 and 4.7, and with Cyrus 2.0.15 and 2.0.16 as the mail server. The cyrus sever does not exhibit this behavior with regular mail clients. It has also been tested with php 4.0.4pl1 and php 4.0.6 At this time, I am unable to determine if the issue is with the c-client or with PHP. M. Gamble Echo Online Administration
