[xmail] Re: xmail DNS problem : How I fixed it
After getting lots of mail rejected by Earthlink and others because of
domain name A records instead of MX records, about a year ago I made the
following changes to SMAILSrv.cpp:
In the USmtpGetFwdGateways() function I added the following code at about
line 782:
if ( ppszMXGWs == NULL ) {
MXS_HANDLE hMXSHandle = USmtpGetMXFirst( hSvrConfig,
pszDestDomain, szDomainMXHost );
ADDED: if ( hMXSHandle == INVALID_MXS_HANDLE ) { // fix for failing
toget MX record.
ADDED: Sleep( 5000 ); // wait 5 seconds and try again
ADDED: hMXSHandle = USmtpGetMXFirst( hSvrConfig, pszDestDomain,
szDomainMXHost );
ADDED: }
if ( hMXSHandle != INVALID_MXS_HANDLE ) {
A bit of a kludge but I have not seen the problem since.

[xmail] Add/Delete/Change password for users
I have written a module in C++ (VC6) that uses active directory for xmail authentication. If mail arrives for an active directory user an xmail account is automatically created with default settings. The password is not stored in any .tab file. If an active directory user checks mail an account is created in the same way. This is compiled as part of xmail, it is not an external program. It involves adding a call to the authentication module from UPopBuildSession( ) for POP3 and a call from SMTPCheckForwardPath( ) for SMTP authentication. I have been using since version 1.20 with no issues.

[xmail] Re: Attachment stripping filter?
I wrote one that I have been using for a couple of years now. It is in C++ for Windows. It quarantines the message and sends a mail notification message to the recipient with info about the message. If the recipient replies to this message the quarantined message is delivered. The process is controlled by a text file containing file extensions and a brief description of the file type of the attachment (the description is for inclusion in the notification message). It has no provision to check size butthat should be trivial to add.

[xmail] Re: DNS entry files
Don't backup the DNS cache. All the entries will probably expire before you ever have to restore it. The cache is a convenience, not a necessity anyway. If you are using an external DNS server all the entries are cached there anyway. The DNS cache I was referring to was the XMail dnscache directory andI looked at it with explorer. The Microsoft DNS server cache always has atrailing period in its Cached Lookups entries as shown below (if the graphicis not removed by the list server) [IMG] This is a listing output from the Microsoft DNSserver: NameType Data advance datafull mrse telecentro (same as parent folder) NS athea.ar.

[xmail] Re: DNS entry files
Yes Windows will not allow trailing spaces or periods in file or directory names. I have just checked my DNS cache. There are 20986 entries and none endin a period. I am using Windows 2000 server and XMail 1.21. CreateFile() removes trailing spaces and periods from file and directory names as your link points out. XMail uses fopen() to create DNS cache files. FILE * pCacheFile = fopen( szFilePath, wt ); This function also strips trailing spaces and periods. Where are the trailing periods coming from. It looks like XMail should be unable to create these type of files. At 01:19 PM 07/06/2005, you wrote: The trailing period is quite legal and indicates that this is a fully qualified domain name and no local domains should be appended when trying to resolve the name. If the trailing period is not present the DNS resolver will append local domain names before resolving the name. Thank you very much Tom for the explanation of why there is a period on the end. However, this doesn't help me with the fact that Windows does not like file names with periods on the end. It certainly is not even the Windows 8.3 convention which is normally used for compatibility across platforms. There isn't much I can find that refers to compatibility with Windows and a period at the end, but it is obviously a problem and not supported by Windows. http://support.microsoft.com/kb/q115827/[1] http://msdn.microsoft.com/library/default.asp?url=/library/en -us/fileio/fs/naming_a_file.asp[2] The result is that I can not back up the hard drive which contains XMail without throwing errors. I can not delete, rename, or move a file with a period at the end with Windows. If I could, this wouldn't be an issue because I'd just recourse the DNS cache folder and delete anything that has this condition.
