RE: Cannot send mail

["Karl Mueller" <karlm () acshelp com>]

A while back I had the same problem. Turns out the SMTP proxy on the
Watchguard throws out that error when an email address is denied by the SMTP
proxy. Check out the properties of the SMTP proxy: in the Watchguard firebox
manager, open the SMTP service, Properties tab, Incoming... Button, then
Address Patterns -- make sure Allowed From: is * if you want to receive
email from anyone, and Denied From: doesn't contain any addresses you want
mail from (this is what my firebox III's config says, so YMMV). 

Basically Watchguard provides a pretty granular filter for email addresses
allowed/denied through it's proxy (which seems a little useless because of
spoofed email addresses, but still).

Hope this helps!

Subject: [fw-wiz] Cannot send mail

Hi firewall wizards,

I have just finished building and installing an email server for our
library. I am home using Thunderbird client. I am connected to my email
server at the library. We have a watchguard firewall. I am attempting to
send email and here is the error message I get.

"An error occurred while sending mail. The mail server responded:
Requested action not taken: mailbox name not allowed or chunk too large.
Please verity that your email address is correct in your Mail preferences
and try again."

What do I need to do to get started fixing this problem? Thanks for your
help.
