Subject: Error 550

[Reply] [ReplyQuoted] [Headers] [Print]

Newbie to Linux here so go easy. Also, since I can only say this once, it's my first public forum post in >20 years.

I have Apache2 and Citadel/Webcit-https installed and working on a virtual host with Ubuntu 20.04.

The email problem is there are always two "To: ..." sections included in the email header, which results in email getting kicked back by some servers with:

  Delivery Status Notification (Failure)

  ... (550 Messages should have one or no To headers, not 2. )

This happens with entirely webcit internal email (i.e., no external email client touching the message). And identically, when replying to a message from an internal user or from an external email address message.

An example Header looks like:



  Date: Sat, 13 Feb 2021 13:19:18 -0700



  Subject: Test admin-->mgolden

  Message-ID: <>

  From: "admin" <>

  MIME-Version: 1.0

  X-Mailer: WebCit 927

 Content-type: multipart/alternative; boundary=""


The first "To:..." is always the email address of the logged-in citadel user, whether it's a new message or a reply. The second "To:..." is always the intended recipient of the email..

Am really hoping to make Citadel work for us but this creates a no-go situation b/c I seemingly can't fix it or find a workaround.

[Reply] [ReplyQuoted] [Headers] [Print]

In the movie The Secret of My Success, Brantley Foster (played by Michael J. Fox) expresses the exact thought that goes through every new graduate[he]#039[/he]s mind: "How can I get any experience until I get a job that gives me experience?" The hardest thing to do when starting a new career is to get experience. Often this creates a paradox. How do you get work with no experience, and how do you get experience with no work?
