Scalix Forums

Some of my users get the following error when trying to send email ?
Is scalix blocking the mail ?

"The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'addrupdate-30065233731-26606155--56575 ... .plaxo.com'. Subject 'Re: Your latest info', Account: 'Work', Server: 'scalixmail.pitchpointsolutions.com', Protocol: SMTP, Server Response: '550 Denied due to spam list', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79"

Which client are your users using ?

Denied due to spam list indicates that the connecting client doesn't meet any of the rules that allow relaying to an external address.

If it's SWA, you need to make sure that the IP address of the SWA server is listed in the SMTP Relay configuration file /var/opt/scalix/sys/smtpd.cfg.

If it's another IMAP/POP client, they should be authenticating with the SMTP Relay or have an IP address that matches one of the RELAY accept lines in smtpd.cfg. I'd advise authentication because it's a more secure approach.

one client is using thunderbird and another outlook express.

at least for T'Bird, I woudl recommend using SMTP Authentication. This is enabled by adding a "AUTH_SUCCESS accept ALL" line to smtpd.cfg, just before the RELAY Log_reject ALL line.

then, setup Thunderbird to use your Scalix username and password to authenticate before sending.

WIth OE, this might also be possible, unfortunately, SMTP authentication is broken in various versions. If you have one of those, you will need to allow relaying by IP address. Again, smtpd.cfg is your friend.

When making changes to the file, don't forget to restart your SMTP relay to activate them.
