Read all faq from ezmlm, and you found your solution. Anyway, here is my contribution:
Go to server-manager, into mailing list, choose the list you want, and go to configuration.
Under "Mime types to strip from all outgoing mail:" erase all content. This allow you to send any type of file (ZIP, DOC, EXE, HTML...)
Under "Headers to add to all outgoing mail:" add the following line:
Reply-To: yourlist@yourdomain.com
This allow to reply to list, and not to sender email.
Under "Headers to strip from all outgoing mail:"
add:
reply-to
return-path
to strip from header.
Now, go to /home/e-smith/files/ezmlm/lists/yourlist/msgsize and change 1024000 if you want atach up 1Mb. See the other files to view your configuration.
If you want to create new lists with the same setings, go to the master files used to create the list at /etc/ezmlm/ezmlmrc and edit with your setings. For example search the string msgsize, and chage the default 30000 to 1024000. The strip mime and headers can be edited, but in this case you use the variables.
For example, to change the REPLY TO I explained above, search string </headeradd#E^0/> and add after:
Reply-To: <#L#>@<#H#>
If you read the entire and exelent documentation, you see L represent list, and H represent HOST.
Ezmlm is the best mailing list for me. Later you can publish in the web your message with mhonarc.
Good luck
