Although the *dtaara or CHGPOPA can be used, keep in mind that it might not be 
a good idea to use either. If your attachments are so large that they're being 
split, then it's possible that they shouldn't be sent as attachments. In fact, 
if you cannot guarantee the behavior of all the e-mail servers your e-mail 
passes through, then these should not be sent as attachments but should be sent 
via FTP or other means.

A major point behind the split in the first place is that e-mail systems 
commonly have limits on the allowed size of attachments. Maximum size might 
range anywhere from maybe 500KB to 10MB or more. Your 1000-page PDFs could be 
simply discarded along the way and you might never know, depending on exactly 
how the particular e-mail system responds.

SMTP is an inefficient means of sending such files, inefficient for the client, 
the server and the network. For example, any MIME conversion at both ends takes 
processor cycles and the resulting size increase takes away from network 
bandwidth. Within an internal network, it might be a small or even trivial 
problem. But if the e-mail goes out through the Internet, you might lose 
something without warning. Possibly unlikely nowadays, but still possible.
