Solved Haraka - View Closed Connections
We are using a LAMP App that uses email piping and access via IMAP and or POP3 and getting errors "Error: cannot read - connection closed".
Is there a way to research this in the Haraka logs to view why the connection might be closed?
@JLX89 So the LAMP app is using IMAP and POP3 to access some mailboxes which are hosted in Cloudron ? Both these protocols are implemented by dovecot and not by Haraka. Dovecot logs are in
/run/dovecot/dovecot.logof the mail container. You can
docker exec -ti mail /bin/bashand then inspect the file.
Have you just tried simple
openssl s_client -connect mailserver.domain.com 993from LAMP app's web terminal ? Does it connect?
@girish I've found the following, looks like it just drops for around a minute and then works again.
Mar 02 19:16:21 auth: Error: LDAP: Connection lost to LDAP server, reconnecting Mar 02 19:16:21 auth: Error: LDAP: Can't connect to server: 172.18.X.X:3002 Mar 02 19:16:23 auth: Info: ldap(firstname.lastname@example.org,149.28.X.X,<T6POp+/1YuCVHCuj>): Aborting (timeout), we're not connected to LDAP server Mar 02 19:16:24 auth: Error: LDAP: Can't connect to server: 172.18.X.X:3002 Mar 02 19:16:25 imap-login: Info: Aborted login (auth service reported temporary failure): user=<email@example.com>, method=PLAIN, rip=149.28.X.X, lip=172.18.X.X, >
@JLX89 In the mail container does
telnet 172.18.0.1 3002work ? (that is the LDAP server) . It should look like this:
# telnet 172.18.0.1 3002 Trying 172.18.0.1... Connected to 172.18.0.1. Escape character is '^]'.
@girish Yeah, that seems to be working.
telnet 172.18.0.1 3002 Trying 172.18.0.1... Connected to 172.18.0.1. Escape character is '^]'.
@JLX89 can you check if
supervisorctl restart dovecotinside mail container helps? Otherwise, if you write to us at firstname.lastname@example.org , I can take a look. It's not clear why it cannot connect to the LDAP server. It's really just connecting internally ...
@girish Thank you -- that actually seems to have solved the issue for now!
