  • Non-SSL Email Issues

    Hi all,

    Wondering if anyone has seen similar in the past or recently - When clients are using non-SSL ports it seems there is a delay in downloading emails. It takes a good while for it to even make a connection or it will eventually time out. If using SSL ports such as 995 then no problems at all. Apparently it started over the weekend - Can't seem to figure out what it is. I've tried restarting the services and server and the problem still occurs.

    I'm trying to get clients who have the problem to switch over to the SSL ports but a solution would be handy.

    Cheers,

    Hi Bertie

    Many thanks

    Is there anything shown in mail logs at all for issue

    Does it just happen on mobiles or email clients (such as Outlook etc..) or both

    Is it same issue for all clients or just some

    What version of IW are you using

    Have you tested the connection using a command prompt, if so, how quickly does the service repond (telnet your-ip-address 25 and telnet your-ip-address 110)

    If just some clients see this issue, how big are their mailboxes

    Many thanks

      Hi John,

      Could you remind me which log file actually contains the parts where if a user does try to log in? I'm so used to exim that I often forget how qmail works with the log files.

      From what I can gather from clients

      - Seems to be multiple clients from different domain names, devices don't seem to matter. I've been personally testing Outlook on Windows.
      - InterWorx-CP v6.4.1 (I know it's not the latest but this issue occurred at the earilest on Friday)
      - Telnet seems to come back fairly quick if not instant

      telnet *removed* 110
      Trying *IP Address here*...
      Connected to *Removed*.
      Escape character is '^]'.
      +OK <31562.1584975479@*Removed*>

        Hi Berie

        Best to login to nodeworx, system, logs, mail and look at pop and smtp logs

        These will give date/time stamps whereas looking at raw logs, you woudl need to convert to date/time stamps

        Are they showing large wait times from a user logging in to say sending email

        A fuller test from telnet as below

        Does this show any delay - your initial telnet shows normal as been instant (or near instant) so no issues with service at server level

        Many thanks

        John

        telnet your-ip-address 25
        rset
        helo yourdomain
        mail from:email address
        RCPT TO:email address
        data
        Subject:Your Subject (remember to press enter twice)
        type message
        to finish type . and enter

          Looking at the logs I'm seeing a lot of:



          Mar 23 15:45:19 ipanel spamd[9170]: spamd: connection from 127.0.0.1 [127.0.0.1]:40889 to port 783, fd 5
          Mar 23 15:45:19 ipanel spamc[16912]: connect to spamd on ::1 failed, retrying (#1 of 3): Connection refused

          Could it be related?

            Hi Bertie

            Many thanks

            I do not think that is the issue, and I think the later IW version corrects the spam connect failure (SA I believe trying to use IPV6 and/or not localhost first for connection) - I have not seen that since

            I woudl restart server and test again

            Did you try to send a test email by telnet - if so, was it instant or any delay

            Thinking about it more, is the seen delay on the initial connection - if so, what RBL checks do you have listed (thnking the delay maybe an RBL connect timing) - if not, where does the delay happen ie after initial connection and sending

            Many thanks

              Update -

              Managed to resolve the issue thanks to Interworx support. There was a missing PTR record on the server name clients use to connect to the mail server and also a nameserver in /etc/resolv.conf which was not working correctly. Fixed both and it is now instant connection to the server.
