SUMMARY
Users on your Microsoft Mail system may encounter the error "Notice
16, Error reading mail" when attempting to read a piece of mail, or if
they are seeing duplicate headers in their mailbox for a single message.
Verify that the source of the mail was outside of your postoffice (for
example, from a host-based user).
This error is almost certainly caused by a missing or duplicate -P0xx
option, or a missing -V20 option. Check both of these options as follows:
- Verify that each external process running against your postoffice
is using a unique -P0xx value: the gateway programs all have unique
values by default; however, each External program must have a
distinct value specified on the command line.
- Check that you do not have a mix of version 2.0 and 2.1 external
processes running against your postoffice. If so, use the -V20
backward-compatibility option on the command line of the version
2.1 programs.
