Hi Sam, OK, to sort out what will cause the problem, I've done the following: --> I've pumped up the memory to 512MB. --> Stand-Alone. Only Courier is running on it with IMAP,IMAP-SSL,MTA,MTA-SSL,AUTHDAEMON
Let's see what is happening. Sam, is there anything else what I can provide you, or what I should configure. Please let me know what I can do else, because it is very important for me to get rid of this issue. I want avoid to set up a new MTA (ex. EXIM, sendmail, etc), because I like the Courier product. So give me some hints, if I should trace something, tell me. I can setup an separate instance where you can have access to help me to fix that. Because I want support you to get that product stable and that this will help other customers as well to be satisfied with Courier ;-) Many Thanks.
