Problem relaying quoted "" recipients in sendmail

[Christian Maxeiner]

Last week, orbz.org has tested my mail relay (sendmail 8.8.6/hp-ux11.00) if it is an open relay. Normally my sendmail doesn't relay, but if you put the recipent in quotes "" it does relay to where you want. Has anybody heard of this problem?
I don't want to upgrade to 8.9.3.

Hi Christian,

What is causing the recipients to be quoted in the 1st place? There are mechanisms within sendmail.cf for ignoring quotes for delivery agents (F=s flag), but you may need to run the addresses through the ruleset tester to isolate the problem, or run in debug mode.

Rgds, Robin.

Hi Robin,

thank you for your answer. Normally the addresses are not quoted, but orbz did this in their open relay tests.
Do you have a rule set for ignoring those quotes?

Hi Christian,

There is a dequote map which can be used to remove quotes around tokens.

Have a look at:
