    Missing mail folders

    I am running Mercury 4.8 (on a Windows 10 machine) and all client devices use IMAP4 to access mail.

    I have had problems for a few weeks now and have been unable to solve them.

    When I access mail using Thunderbird 52.4.0, both the Sent and Sent Items (used by different client devices) are greyed out.  If I try to open one of these folders, although there is a list of messages, if I try to open any of them, the server reports that there is no such folder.  If I go to Thunderbird's Subscribe option, although Sent and Sent Items are listed, there are no checkboxes alongside them and they are shown in grey.  There is also a folder with the name of something line iiiiiiiiiiiiiiiiiiiiiiiiii which has a checkbox.  I never intentionally created a folder with this name on the server.  There are a few rather old accessible messages in this folder, as viewed by Thunderbird.  If I access mail from an Android phone Aqua Mail) two Sent and one Sent Items folders are showing, all of which show lists of messages.

    Another, perhaps related, issue is that, for the account in question, I automatically forward (using Mercury's filtering rules) all mail to a GMail account, as a backup.  Unfortunately, if the forwarded message contains an attachment, the message is forwarded but not the attachment.  One other curious things is that when mail is sent from the non-GMail account the Sent copy sometimes (I don't think that this is consistent) ends up in the GMail Sent folder. 

    There are a dozen of so accounts set up on the Mecury server, but it is only one that displays the above problems.

    Presumably something has been corrupted.  I have done a low-level hard-disk check for the disk being used by Mercury and it passed both short and long tests.  This was using SeaTools for the Seagate drive in question.  I have also done a full virus scan (Avast) and malware scan (Malwarebytes) and no problems were reported.

    Maybe I have lost my Sent/Sent Items messages, if the folders no longer exist.  However, any help to investigate the above problems would be appreciated.

    Re: Missing mail folders

    Try switching on session logging for MercuryI briefly to see exactly what commands are sent from different devices and what the server responds. Check the mailbox directory for the user in question to see if there is something unexpected with the number of folder files (extensions PMI and PMM) .

    Re: Missing mail folders

    Thanks for the reply Rolf.  Where do I find these PMI and PMM files?  I have looked on Mercury\Mail\The_User_in _Question and don't see any.  There are only CNM and PMN files.  I must be looking in the wrong place.

     

    I am using IMAP4 by the way.

    Re: Missing mail folders

    OK, I have found the files and can see some problems. I'll post again when I have looked more closely.

    Re: Missing mail folders

    I have made some progress with this issue,

     Using  mbxmaint (GUI version) on the account in question, I found 9 files associated with the user account in question (See below).  Of these, 6 checked out OK.

     Of the other three, one was indicated as having messages with non-unique IDs.  I corrected this using mbxmaint's Fix IDs function.  The size of the file was 567MB

    The other two caused the following message to appear in mbxmaint:

    !! Found internal consistency error:
    #014 Location indicated in master file is out of bounds

    Both of these files were quite large; 480MB and 215MB. 

    The first line of some messages in these two files begin with ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ 

     

    Thank you

    Gordon

    Re: Missing mail folders

    There are sufficient things going wrong with my current Mercury installation, viz corrupted folders, messages disappearing of their own accord, the wrong message sometimes appearing when a message is selected, messages forwarded to GMail (through Global Filtering) having missing attachments, that I am contemplating reinstalling Mercury from scratch.  Before I do this, I would like to be clear about a few things:

    • Can I run a second instance of Mercury on the same computer?  I think I can, as long as Mercury has a different root directory or is installed on a different hard disk.
    • Does Mercury set up the standard initial folders itself or is this done by mail clients? I am asking tis because, when I set up a new user in the current Mercury installation, and then connect to it (IMAP4) with Thunderbird, only two folders show up in Thunderbird; Inbox and Trash .... no Sent, no Drafts, no Archives etc. Furthermore, although Inbox shows up, it is shown as Unsubscribed by Thunderbird.  This doesn't seem to prevent it receiving test messages.

    Thank you

    Gordon

    Re: Missing mail folders

    The answer to your question about running two instances of Mercury on the same machine is yes.  I run one from C:\MERCURY and one from C:\MERCURY_E. 

    I can't answer your second question.

    Re: Missing mail folders

    Thanks Brian. I will install a second instance of Mercury on my server machine and see what folders are automatically created when I connect with Thunderbird. That may answer my second question.

    Re: Missing mail folders

    A couple of our staff use Thunderbird with IMAP to connect to Mercury/32 and the only extra folder that is created is Trash (or whatever Thunderbird calls it). Everything else needs to be subscribed to.

    Re: Missing mail folders

    Thanks Greenman. I have installed an additional instance of Mercury and you are correct, when using Thunderbird only Trash is initially created, in addition to Inbox.  However, as soon as a message is sent, the Sent folder is available and as soon as any message is saved, the Drafts folder is available.  So far so good.

    However, there is an issue of two separate instances of Mercury listening on port 25 for arriving mail.  Obviously that doesn't make sense, as a thing to do.  On the IMAP side, everything seems OK, as I have made the second instance of Mercury use port 1143 rather than the usual 143.

    Re: Missing mail folders

    I am far from a Mercury expert so will share by setup in the hopes that it provides some clues.

    My first instance is running modules D, C, & I.  Module D handles retrieving mail from hosted mailboxes, Module C handles forwarding per filters and forward files, and Mercury I handles IMAP access by our outside people.

    My second instance is running modules E & S.  Module E processes outgoing messages queued by Pegasus Mail clients.  Module S provides an SMTP server for sending by our outside people.

    Re: Missing mail folders

    Thanks Brian.  What you are doing makes complete sense to me, as you are only running one instance of Mercury D.  I am now rebuilding my server using the new installation of Mercury.
