What were you running before?

Mail clients are often bad at giving feedback about errors.
How does "nc -vvc mail.host.name 993" look?

To help diagnosis:

Does a plaintext connection on 143 work?
If not, does a plaintext connection work if you disable SSL/TLS in Courier?
?

Courier imap not accepting connections after update to -curent

2018-11-19 Thread Theodore Wynnychenko 
Hello 

I just updated to -current using a snapshot. 

I then updated packages (pkg_add -vui), which updated courier-imap. 

pkg_info | grep courier 
courier-authlib-0.68.0p4 authentication library for courier 
courier-authlib-mysql-0.68.0p3 mysql authentication module for
courier-authLib 
courier-imap-4.18.2p0 imap server for maildir format mailboxes 
courier-pop3-4.18.2p0 pop3 server for maildir format mailboxes 
courier-unicode-2.0p0 courier unicode library 

Courier does start, and is listening for imap-ssl connections: 

netstat -an | grep 993 
tcp 0 0 *.993 *.* LISTEN 
tcp6 0 0 *.993 *.* LISTEN 

I can also confirm the port is open from the connecting machine. 

However, mail clients cannot connect to the imap server.  They indicate the
server is not responding. 

Nothing in the configuration has changed since the update occurred. 

The imapd does use its own access file, so I tried commenting that out, and
restarting, but there was no change. 

It is listening, but does not accept connections. 

Not knowing what else to do, I downgraded to a previous version (the
packages associated with 6.3), and re-enabled the access file.

pkg_info | grep courier 
courier-authlib-0.68.0p3 authentication library for courier 
courier-authlib-mysql-0.68.0p2 mysql authentication module for
courier-authLib 
courier-imap-4.18.2p0 imap server for maildir format mailboxes 
courier-pop3-4.18.2p0 pop3 server for maildir format mailboxes 
courier-unicode-2.0p0 courier unicode library 

And, it works again, accepting connections from mail clients. 

But, this seems like a poor solution. 

If anyone has an idea of what I can try to get the current version of
courier working, that would be great. 


Thanks
