creating webmail with cf5.....mimeattach

[afterdigital]

Hi everyone,

I am in the process of creating a webmail based program. I am using linux (redhat 7.2) with sendmail, mysql, etc.

Without overextending this message, what would be the best resource for me to understand 'creating webmails' such as mailboxes, attaching files, downloading attachments, different domains, etc.

Thanks in advance,

Javier
