Hello all, I finally had to register rather than reading the threads because I came across an issue that I cannot figure out. Here is what I have... Fedora Core 5, running ispconfig with postfix and spamassassin (spamassassin is not very well configured due to lack of time so it really isnt doing anything as of yet). This has been running for several weeks without a single hitch. Until this morning. It seems as though incoming email is getting lost somewhere, but I cannot find where it is going. I have another mail server and I can read in the logs where mail is being delivered to the postfix server, but when users check their mail, there is nothing there. There is no problems with logging into their mail accounts, everything seems fine. Just no mail. Anyone encounter a similar issue? And have some information on where I should take it from here?
