- Subject: workaround for 4K buffer on most sendmails

-
- We've run into a problem at the EPA that involves receiving messages
- with very large "To:" fields. Agency policy is to list all the
- recipients of a message, rather than use aliases, and some
- distribution lists have 200+ users on them. Most of the distribution
- lists live in the Agency's standard e-mail system, All-In-1, on the
- VAX. Messages are forwarded to SMTP systems within the Agency by
- a gateway system which converts protocols from All-In-1 to SMTP.
-
- We found that 80-90 usernames in the "To:" field fills the buffer that
- sendmail uses to process the header. On Suns, the MAXFIELD definition
- in conf.h is 4096, as it is in DG/UX, a SysV R4 based UNIX.
-
- Put on your thinking caps: any suggestions on how to get around the
- 4K header limitation? We've gotten a patched version of sendmail
- from Data General, but that solution will require every UNIX box in
- the Agency to get a similar patch from their respective vendors and
- maintain it from release to release. Politically, limiting the
- expansion of the distribution list is not an option. (and political
- constraints are as real as technical ones....)
-
- Any good sendmail wrappers or mail processing programs that work
- on every UNIX box from Data General, Sun, SGI, DEC, IBM, SCO UNIX,
- etc etc etc. This is not a prefered solution since it involves
- maintaining and distributing the wrapper on all the UNIX system.
