Mail problem

[Dave Burton_1]

I'm having a problem sending mail to certain users. I'm pretty sure it's related to the presence of capital letters in the username, but can't figure a workaround.

If I create a user mailtest (no capitals), I can mail that user no problem. But when I create a user MAiltest (leading capitals), I get 'user unknown' errors when I try to mail them.

The policy here has been to create usernames in the format DBurton. Surely I don't have to drop and recreate these users.

I've tried enclosing the username in single and double quotes with no joy. Can anyone help?

Here's output from a verbose sendmail command.

You nedd to configure sendamail, in order to user USERNAMES.

IIRW ( not sure at all) , find this line in /etc/mail/sendmail.cf and add a 'u';


Mlocal, P=/usr/bin/rmail, F=lsDFMAw5:/|@m, S=10/30, R=20/40,
T=DNS/RFC822/X-Unix,

-----

Mlocal, P=/usr/bin/rmail, F=lsuDFMAw5:/|@m, S=10/30, R=20/40,
T=DNS/RFC822/X-Unix,


I cant find the correct man.... Sorry.

Hi Carlos,

To view the link using europe-itrc, substitute europe-support in place of us-support in the link. Here is the doc,

//quote//

By default, sendmail downshifts everything in an incoming address into lower case, to avoid any difficulties when a sender capitalizes part, or all, of the name. To turn off the downshifting, the options that are passed to the mailer program in /etc/mail/sendmail.cf need to be modified, in this case, rmail.

Looking in at the Mlocal configuration, there will be something similar to:
Mlocal, P=/usr/bin/rmail, F=lsDFMAw5:/|@qm9, S=10/30, R=20/40,

This would result in:
>sendmail -v TEST TEST... User unknown

If this is modified to be:
Mlocal, P=/usr/bin/rmail, F=lsDFMAw5u:/|@qm9, S=10/30, R=20/40,

Note the "u" in the "F" options section

This will give:
>sendmail -v TEST . TEST... Connecting to local... TEST... Sent

//endquote//

Hope this helps.
