[horde] How to do SMTP Authentication with horde groupware webmail

[Suhag P Desai]

Thanks Niels,

As per the http://wiki.horde.org/FAQ/Admin/Config, Horde and IMP can support
SMTP authentication, but only if the SMTP server take the same
authentication credentials as the POP/IMAP server (which would generally be
the case). Simply edit the Horde configuration as per the comments in the
Mailer tab of the setup interface.

Above statement is differ from what you referring. 

As you mentioned in your last para, Suppose we use same username and
password in SMTP auth, we will not have accountability for every user.

Many Thanks,
Suhag.

Dear Suhag,

i'm just wondering if you really want to detect "spam" in mails sent by your
users / over your webmail system. This sounds very unusual for different
reasons.

Typically you configure within your MTA/MDA<->spamfilter couple which mails
are treated by your spam filter and which not. Many solutions are configured
by default to not treat any mail from "localhost" and/or authenticated smtp
connections. This means the correct way/point to configure this should be
your MDA or spamfilter (depending from the solution and combination do you
use) but not in your MUA horde.

In Horde IMP you can configure within the web administration GUI if horde
should call the "sendmail" (or sendmail compatible) program by shell or send
mail by SMTP (with or without Auth). If you have horde only on that system
you may can avoid smtp auth (typically most MTAs accept unauthenticated SMTP
from/to localhost).

One option is to use a single "special" smtp account (i.e. you name that
user "smtplocal") in Auth for each SMTP connection. In Horde see
./imp/config/servers.php for configuration examples and configuration of
your SMTP-server connectivity. In most setups it is not required that you
have to use the personal credentials of the WebMail user (and at least in
some Horde has no access to it) to get his email sent.


best regards,

Niels.
