I realize this question should be posted elsewhere, but I need further info from people; involved with Netscape in order to debug a performance problem I've had since this sendmail upgrade. I am asking the question here in the hopes that someone can tell me what netscape (V4.75) is doing behing the GUI when the "sending login auththentication information" popup comes up. If I knew that then I'd have a better shot at finding out what's wrong. We have a performance problem; relaying and sendmail works but seemingly more slowly than it used to.... Since a recent upgrade from AIX 4.3.2/sendmail 8.8.8 to AIX 4.3.3/SENDMAIL8.9.1, our users are seeing a delay in the dispatch of mail after hitting the send button in Netscape Communicator 4.7. What we're seeing is a popup window saying something to the effect of "sending login auththentication information" briefly (.5 to 3-4 seconds duration) that was never there before. The way our user base works, the PC IMAP clients relay off of our mail server. Before with SM8.8.8 we had one of the elaborate rule changes to prevent indiscriminate relaying (and the blacklist) with the names of the user base's hosts in a file called RelayTo. Now, with SM 8.9.1, the anti-relay stuff is included by default and there's a file /etc/mail/relay-domains that has the list of domains that we allow relay from. I should say that the old RelayTo file that I used with V8.8.8 consisted of hostnames, whereas the new V8.9.1 equivalent file, relay-domains, is use the domain name. I had thought that the authentication mentioned in the popup might have been just checking to see if hostname was a member of a domain, but I've come to think not since : 1) adding a fully Qualified host name doesn't seem to make relaying mail from it any faster and 2) the domain is necessarily at the end of the FQhostname anyway. An added problem in debugging this is that this slowdown is variable: sometimes the popup doesn't show (maybe because the authent happens so quickly?) and even when it does, it can be just a flash OR stay up for as long as 3-4 seconds Anyone related to Netscpe development able to tell me what Netscape is doing when it dlashes this popup?
