Configuring Exim on Cygwin for SMTP service provider authentication

Hi

I'm quite new to Exim & Cygwin.

But I could successfully download & install Exim on Cygwin with my Windows XP SP2.

I'm trying to configure exim (4.69) to send mail thru my service provider(SMTP). But my service provider requires a user/password for SMTP authentication & i'm unable to configure this.

var\log\exim\exim_main.log shows the following error

2009-08-26 10:59:33 KOYXX3-00023K-P0 ** user [at] domain R=send_to_gateway T=remote_smtp: SMTP error from remote mail server after MAIL FROM: SIZE=3241: host remote_mail_server [xx.xx.xx.xx]: 530 5.7.1 Client was not authenticated

My windows XP system is on a local domain (domainA.com) & my service provider is on a remote domain (domainB.com). I just need to transfer all the mails from exim over to the remote domain.

Any help is appreciated.

Thanks

OK, add a router like:

outgoing:
driver = manualroute
domains = ! +local_domains
transport = domainB_auth
route_list = * outgoingMta.domainB.com

Have a transport like:

domainB_auth:
driver = smtp
hosts_try_auth = mta_domainB_auth

In your authenticators have:

begin authenticators

cram_md5:
driver = cram_md5
public_name = CRAM-MD5
client_name = "${extract{auth_name}{${lookup{$host}lsearch{/etc/exim/smtp_users}{$value}fail}}}"
client_secret = "${extract{auth_pass}{${lookup{$host}lsearch{/etc/exim/smtp_users}{$value}fail}}}"
plain:
driver = plaintext
public_name = PLAIN
client_send = "${extract{auth_plain}{${lookup{$host}lsearch{/etc/exim/smtp_users}{$value}fail}}}"

# The file /etc/exim/smtp_users contains lines like:
# mta_domainB_auth: auth_name=my_username auth_pass=secret auth_plain=^my_username^secret

This should work but because you are only dealing with a single isp smtp
server it would be easier to not use lsearch and do something like:

begin routers

smarthost:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
# rogers
route_list = * smtp.broadband.rogers.com byname

begin transports

remote_smtp:
driver = smtp
# b.c.s.i. - we have to authenticate against this smarthost
# rogers
hosts_require_auth = smtp.broadband.rogers.com

begin authenticators

# b.c.s.i. - used to authenticate to smarthost
fixed_login:
driver = plaintext
public_name = LOGIN
# rogers
client_send = : account-name [at] rogers : account-passwd

And just put your authentication info in plain text.

Cheers.
