I installed a pure mailserver in an multiserver enviorement, no spamassasin, dovecote etc. used or installed. Just postfix. Should be used as mail dev null device to reroute all mails to nonexistng users to suppress non delivery notifications filling mailqueue in case of faked sender. Monitor show red in case of missing pop3 and imap service, ISPConfig shall not care about pop3 and imap not running on this specific server. Thanks for help Rainer By the way, is there a newer version of ISPConfig 3 manual. There are quit a lot of things not up to date. IF there is I'll buy. mk
A ISPConfig mail node has pop3 and imap and ispconfig warns if it is missing. So your setup is not supported and therefor causes this warning, you will have to live with that warning or you have to modify the ispconfig code.
