MMDF and Sendmail Control A's

Strangely enough, SCO's sendmail looks to MMDF's mmdftailor file for its mail separator characters, and will surround messages with Control-A's if these aren't set:

MMBXPREF    ""
MMBXSUFF    ""
 

SCO and sendmail have an unfortunate history. Most SCO systems were configured with MMDF - sendmail was available, but mmdf was more often used (see replace mmdf with sendmail).

When sendmail was used, it was often an older version, rife with security problems, and troublesome to replace. That hasn't changed. Compiling any app on SCO is likely to be difficult and sendmail is of course no exception. Searching for pre-built sendmail binaries is often the easiest path.

Sometimes SCO patches update sendmail somewhat and checking http://www.sco.com/support/security/ might get you somewhere too.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
