Cannot send outgoing mail when I set default address to :fail:

[zaggs]

Hi guys,

When I set the default unrouted email address to :fail: I am not able to send outgoing mail. However, if I change it to :blackhole: it works fine again.

Any ideas what to do?

i dont think there si any relation in sending mails and setting to fail .If you set default address to fail the unrouted mails will be bounced back . Its better to set it to blackhole or set a default catchall . Kindly provide us the error that you get while sending mails .

I would most certainly not use :blackhole:... :fail: is by far a better option

I have some very busy mail servers and this makes a radical difference... Thanks Chirpy

As far as the problem goes, I have also had complaints about this from some users. I have had them kill and recreate the accounts and it seems to clear up the problem. I have no idea what the issue is however...

When you are sending out e-mail, are you using a valid e-mail address on the server to send out from?

If example.com exists on your server and you are using mail.example.com as your outgoing mail server and you are sending out mail from bob@example.com. Exim on your server (mail.example.com) will see that the domain you are sending from (example.com) exists on the server. It will then check to make sure that the e-mail address you are sending from (bob@example.com) exists on this server. If it does not then the transaction will fail, because the sender verification process will fail. If you do not have the bob@example.com e-mail address set up, then the default box will be checked. Setting your default box to :blackhole: is the same as accepting the e-mail just not delivering it anywhere. So in this situation, any e-mail address on the example.com domain will be seen as valid. When the default box is set to :fail: only those addresses that are set up as actual mail account and/or forwarders will be accepted.

Basically, you need to insure that you are sending mail from a valid e-mail address that can also accept e-mail on the server.
