Another question.  I'm looking at replacing Captaris WebMail with SquirrelMail.  I've gone so far as actually sending a test message from SM.  Does anyone know if it's possible to remove the SM identifiers from the header records?  I don't personally but I'm sure there are plenty of mail administrators out there that are blocking SM due to all the spam with SM in the headers.

Good point - thanks. Mercury is running on Windows Server 2003 and somehow there was two instances of MErcury showing in Task Manager, although I could only see one on the screen.

 

Fixed.

 

Thanks again,

Andy.

This was a user error ! [:$]

The user sending the email had missed one letter out of the domain name.
I had check and completely missed it as well !
 
So mercury did the look up and found the IP address of this new misspelt domain.

All resolved now.

Many Thanks

Thanks David. I basically knew the answer when asking the question but wanted to hear from the developer first. I scrounged up Win2K Pro to replace NT4 and TLS works just fine on that. Recent mailing list conversation concerning Mercury running on wine in Linux also prompted me to test that, seeing that I run several linux boxes. I brought up Mercury v4.52 through wine in Fedora 7. I am running with Spamhalter, Clamwall ( with clamav installed on wine too). Everything seems to be working quite fine, including TLS. To keep from having to run as root on the mail server I port forwarded ports 25, 110, etc. to ports above 1023 off my IPCop firewall/router box. Maybe I didn't need to get that Win2K disk after all.

Thanks again,

     Curt

I'm still working on the ports with my Ubuntu setup.  It's not a big deal right now since almost nothing comes in via the external ports and Pegasus Mail sends via the queue.  If push come to shove I'll do this with port forwarding like you have done to ports a normal user can use.  That said, since my Ubuntu system is way behind a firewall/router the bad guys will have a tough time getting to anything on this system even though I am running as root.  Nothing on this system is accessible outside the local lan. 

I was really surprised how well Mercury/32 installs and runs on a Linux system.  I know diddly about Linux and I got this up and running in less than a couple of hours after installing Ubuntu and Wine.

I many times have WinPMail, Thunderbird, OE and Eudora all looking at the same account at the same time using IMAP4 without problems.  All see the same new mail and folders.  There is a problem with deleting since Mercury/32 does not allow deleting when there is concurrent access but I see no other problem. 

I have all sort of problems with Outlook 2002 and IMAP4 , many times it simply crashes when trying to do IMAP4, but right now I have Outlook 2002, Thunderbid, OE, WinPmail all looking at the same account al all see the same new mail.  No problems at all.  Mercury/32 v4.52 running on a HP Workstation.

Yes, you are right. That is exactly the way I think it should work. In fact, it was, prior to 4.52. Oh well, I can try Tbird for a while to see if it grows on me. It may give me the feeling I am on one of my Linux boxes. And any time I get to spend away from MS is good.  Thanks for your input.

As of today Jan. 2010 the problem described still exists.

Server=Mercury/32 v4.72; client=Thunderbird 3.

I could find only one solution to prevent the name of a deleted IMAP folder to reappear forever: edit manually IMAPSUB.PM in the MAIL dir on the server and remove the line corresponding to the deleted folder.

1) I also saw a similar problem revolving around the management of IMAPSUB.PM: I move a message-only folder under a folder-only folder, then it is impossible to subscribe to it. I.e, I subscribe, it shows up, next time I start TB it is gone, must subscribe again.

Cause: IMAPSUB.PM was never modified by my subscription. Yet the account running Mercury/32 has all rights on that file.

2) The renaming of a folder-only folders is also not working (message-only folder can be renamed though): it is refused by the server.

3) the similar issue described in thread http://community.pmail.com/forums/thread/21215.aspx is also still relevant today.

4) the issue on hierarch.pm described in thread http://community.pmail.com/forums/thread/2634.aspx of 2007 is also still relevant today: yesterday I saw that all IMAP sub-folders containing messages were moved (by Mercury?) under Mailbox, the tree structure still appearing in IMAPSUB.PM but emptied.
I.E. all folders in hierarch.pm appeared as :

0,0,"38488A1:165E:FOL0027E","231A164:My Mailbox",...

Looks like it will work if I set it to deliver to a special header only!

 Thanks!

I would but it's restricted here at work, and I wanted to see if my home mailserver backup was actually configured correctly

Dumb.  Ok, the "fix" I did was to create new self-signed certs, but when I did that, the file permissions were only for my login, it didn't inherit the folder permissions of the Mercury program folder.  Very strange.  Ok, so I fixed that.  I guess that is my punishment, better to just live with the periodic SSL errors I guess than to hose myself completely!

[quote user="rhs"]Wouldn't you know it but Netware is "going away" at our institution.  Do you have anything to offer wrt migrating from an NDS environment to one in Microsoft's Active Directory? I checked out the wiki but no such luck there.  I'll search the mail archives as well.  Any pointers, tips, gotchas, bewares, directions would be appreciated.  Thanks!

I just responded here a few days back on active directory and Mercury/32.  There is nothing available right now other than a alpha version of dll to make the connection.  See my post [/quote]

Thank you for your reply. I think you are right, I'll have to start fresh. I allready started collecting spam (492 mails over the last 24 hours, just for my personal account!).

[quote user="David Meyer"]This problem seems to be resolved. I am not sure if it was the dns timeout or removing BitDefender.[/quote]

 

Personally I think it was the latter.  None of the anti-virus programs seem to get the Winsock level stuff right when setting between server and clinet.

[quote] I asked the users to bounce a copy of incorrectly marked emails to the NoSpam address at each site. Unfortunately, the next email from the same source is marked as Spam again. After a few tries the users just stop sending the emails to the NoSpam address and moan at me instead.[/quote]

You have put your finger on one of the biggest dilemmas facing mail admins trying to implement Bayesian filtering in a network - managing user expectations.  I have found this a tricky problem and there are a few different strategies you can try.  Which one works for you may depend of the type of users as much as anything else.  At one site, I have to do all the classification myself because no one stays in post long enough to learn the details.

As Lex suggests, altering the whitelist expiry can help with infrequent mail lists.  Also, have a good read of the Spamhalter.pdf description - particularly the Whitelist/Blacklist section on page 17.

I had the same problem when I recently upgraded to 4.52 and found that if I disabled the "Exit and restart each day after performing daily maintenance" option the problem went away.  I had originally used this setting because 4.01b seemed to have a memory leak on my XP installations which caused Mercury to freeze up after a couple of days.  I haven't yet had this problem with 4.52.  So, that might be something to check.

[quote user="Peter Strömblad"]

We have the same problem, so whenever there is a new version (as a tester there can be a few) I backup the server directory, not the queues, and the pmail.usr file - rest is left alone. Then I shut down the mercury server I'm about to upgrade, check that it is unloaded using both task manager, and file open check - then do any upgrades. It takes less than 2 minutes. Only very few users will see a pop3 connection error due to the upgrade. Normally I do it at 12:20 since most people then are at lunch, whether at home or at the office.

[/quote]

2 minutes sounds very good. Compared to the time, that the regular Windows updates needs, this is really a short time.

I think, the POP3 connection dropouts are not the problem. The only problem I had in the past concerned IMAP connections. Because we work in Netware mode, the users mailboxes are not located on the server where mercury is running. Sometimes we got destroyed folders or hierarchies, when an user is connected by IMAP and I shut down Mercury. It seems that this happens when the user is accessing to a folder in the same moment (moving or deleting mails)

That's why I will do the upgrade today in the evening - on Friday evenings most of the people are watching TV [:D] 

Best regards
Thomas

Today the Mercury GUI is tightly integrated with the operating core. When running services you need to unhook a GUI from direct screen calls (such as status windows etc). When David separates the GUI from the core process, there will be methods to create users, aliases, passwords, do restarts, etc by means of hooks into the core, through an API or similar means. Then it is easier to create whatever admin interface that interacts with the core through standardized calls.

The storage of domains etc, is to make it possible to have multiple installations of Mercury, and multiple domains. Today Mercury is based on a flat structure, but domains and users and aliases actually create a hierarchical structure. We have it organized this way today, but I never made a public software for it. A relational sql-database is perfect for this type of structure. Then it is very little effort to take the info to the flat file structure that Mercury is based on.
