You may wish to change vmysql.c so that if a user pop checks, RBL checks are skipped as well. This appears to already be done by default, unless you use a sql server backend. To fix this for mysql edit the vmysql.c file as follows.
Change line 753 or so sprintf(SqlBuf, "%s:allow,RELAYCLIENT=\"\"\n", row[0]); To sprintf(SqlBuf, "%s:allow,RELAYCLIENT=\"\",RBLSMTPD=\"\"\n", row [0]); Similiar lines appear in the oracle and postgres code as well. The same change in both should fix the problem. Aaron Gee Network Engineering Atlantic Net Aaron Gee Network Engineering Atlantic Net --- Outgoing mail is certified Virus Free.
