I think you might avoid the problem by making sendmail Impersonate your |
| 23 |
isps domain. |
| 24 |
|
| 25 |
Using some or all of these settings in sendmail.mc |
| 26 |
MASQUERADE_AS(`yourISP.domain')dnl |
| 27 |
MASQUERADE_DOMAIN(`youractual.domain')dnl |
| 28 |
FEATURE(masquerade_entire_domain)dnl |
| 29 |
FEATURE(masquerade_envelope)dnl |
