We have a Windows based web system which pops mail from our SME server. Data from these mails is extracted and stored in an MS-SQL database and used is some way by the system. Mails bigger than 4MB cause issues for the system, I dont know what the issues are but I will have to ask the developers if this info is really needed to solve my problem. I have been asked to bounce messages larger than 4MB to system mail accounts but not mails to standard email accounts.
I have been able to do this with mailsorting and custom .procmailrc, however after a system reboot my custom .procmailrc is gone even though I have set geekmode for these users.
I would like to know how to have custom .procmailrc files that dont get overwritten, but still have mailsorting contrib work because we also use the web driven mailsorting for reasons which I am sure is not relevant to this question.
