But - have you tried connecting to the SMTP port via Telnet to verify what is happening manually? 

Interestingly enough - today while searching for SSL errors I get from Citadel - I found the following link:


https://www.linode.com/community/questions/10102/cant-receive-email-with-citadel

Where other people are complaining about the same issue - but also... where people are having trouble with sending/receiving mail.


And the suggestion made by the people trying to help involved connecting to Port 25 via Telnet to see what was happening.


I don't think my error, which is in this guy's logs...

"SSL_accept failed: errval=5, retval=-1 (Input/output error)"

Is related to send errors using SMTP - but it is interesting that it isn't just me getting this error in my logs.

Anyhow - maybe the link above will assist you.

Linodes have 25/tcp blocked by default. If you send them a support ticket and have had the linode for a while they will open it for you. The other thing that worked was enabling deprecated tls 1.0. I had this issue with phpbb also, when I included support for all tls versions including old not recommended ones, it fixed it.

Internet Mail is a pain in the ass to configure and requires a very high level of interdisciplinary knowledge about IT to configure successfully - and once you get it up, it is a magnet for attacks and requires constant diligence in management, administration and security - as well as lots of experience navigating the different providers and authorities responsible at all ends for making it work right. Once you get that all right, your running one of the public faced Internet services with the *most* personal liability. Just ask Hillary Clinton how sketchy it can be running your own personal mail server. I wouldn't do it for a SMB, I wouldn't do it for a personal mail server. In each case, a hosted solution is way less headache. I'd only do it for six figures of compensation from a major corporation with a team of IT engineers and lawyers that I was certain wouldn't throw me under the bus if someone from a TLA .gov org came knocking. 

Citadel makes it easy to set up the mail SERVER... but there is no program that can solve the rest of those challenges. 

This is why I have Citadel Internet mail deactivated.

Thanks for the support !

Just to be clear

- My service provider is not blocking any ports

- I can send email using the webclient to an external emailadres (my company email, gmail, etc...)

- i do receive emails from, numerous external sources, webshops, groups.io etc. etc.

But i cannot use an email client using smtp on several ports - pop3 works - login credentials work fine on pop3

this is what i get accessing port 25 via putty from a windows pc in my local netwerk :

And you get authentication failed with the correct password - but you can log into the web client, authenticate with the same password and userID, and it works? 

That is bizarre. 

Do you have the Citadel textclient set up for Telnet and SSH? Can you Telnet and SSH into your Citadel or do you get authentication errors there, too? 

Bear with me here - because I've been talking with another Admin who had a problem with authentication failing on the text client - and I'm wondering if this could be related to his issue.

Hello I have since yesterday following problem. When I send or receive email I get error in wincit when I try to open this message. The other side gets this message correctly.

some (long) time ago I expressed my interest in trying out Citadel within a Docker container and someone here pointed me to some repository where some sort of "prototype" was available. Now, I have lost that particular link and am now asking if anyone here can (once more) provide it to me?

We ended up going in a different direction.  Instead of Docker, we built an AppImage, which just had its first beta release a couple of days ago.

AppImage, as you may know, packages an entire complex application and all of its dependencies into a single executable file that runs on many different Linux versions.  It turns out we had to change a lot of things that were based on outdated assumptions to make this happen.  For example, we ended support for the LFHS-style build and now require everything in a single directory.  These changes ought to make it a lot easier to put Citadel and its dependencies into a container, but as previously noted, we are not currently working on that.

Go ahead and try the AppImage if it can satisfy your requirements.

bart, have you tried using your full email address as the username?

For example, instead of using "bartv" try using "bartv@bartscorner.nl" instead.

And of course, watch your server logs while this is happening, to see if it mapped you to the correct user.

github was too costly? lol... the source is out there, someone just has to volunteer to maintain

revisited... sourceforge was too complicated? just insult to injury. citadel is a blessing of source code within superb architecture. surely I am not the only one implementing message search and forgot password routines.

Search should be pretty easy because there is already a full text indexer built into the message store.

As for the public repositories ... Citadel pre-dates them all, so we've always managed it ourselves.  Our public "forge" is at https://code.citadel.org/

I encountered this same authentication problem with version 931 built via easy-install.  I think the problem is with citadel/modules/smtp/serv_smtp.c where smtp_get_user(5) is called in smtp_command_loop.  From this context, the offset parameter 5 should be replaced by zero (0).  I modified the easy-install script to work with a patched copy of the tarball and the resulting build seems to work correctly.

I've had to abandon my HMAIL server (Windows XP PRO issues activating)

I have installed a Debian system with Citadel. I am looking to do some relaying of email from specific IP addresses from old devices that cannot handle auth.

Is it possible thru Citadel and can it be done via the web manager? Or will it have to be done via CLI?

Planning on standing up a Citadel at our makerspace

How much support is still in the current version for dialup modems?

You should be able to run the 32 bit image on a 64 bit board. In fact, I would love it if you could try that.
