C# Bulk Mail Download With only 4 mails downloaded

[peterzhou]

// download all messages from yandex via POP3 and add results to the table
Tuple<string, string, string, string>[] allMails;
allMails = ZennoPoster.BulkMailDownload("[email protected]", 
       "ххххххххххх", "pop.yandex.ru", 995, true,
       ZennoLab.InterfacesLibrary.Enums.Email.EmailProtocol.POP3, 
       24*100, 20, false);
 
// loop fo all messages
foreach(Tuple<string, string, string, string> tuple in allMails)
{
    // adding messages to the table called Tabl1
    // tuple.Item1 - sibject, tuple.Item2 - from, tuple.Item3 - html message, tuple.Item4 - text message
      List<string> tmp = new List<string>();
       tmp.Add(tuple.Item1);
       tmp.Add(tuple.Item2);
       tmp.Add(tuple.Item3);
       tmp.Add(tuple.Item4);
       project.Tables["Tabl1"].AddRow(tmp);
}

When I use this to my email and save Tabl1 to aaa.xlsx, I got only 4 mails. I have a lot of mails in my email account. What is the problem(I know little C#)?

Maybe the issue has a solution in this line?

ZennoLab.InterfacesLibrary.Enums.Email.EmailProtocol.POP3, 24*100, 20, false);

From the wiki I see "24*100" is a parameter for:

lastHours
Type: System.Int32
If message older than specified amount of hours will not be returned. Default value is 2 hours

On the wiki there is no mention of the units used for the parameter in "lastHours". Does anyone know what 24*100 relates to? 24hrs x 100 ?


Also the maxCount paramter interger "20", in this line (EmailProtocol.POP3, 24*100, 20, false), should exceed the expected number of emails to download. At the moment, you would only be downloading 20 mails per run, if my read is correct.

I'm not familiar with c#, but on the basis of experience with other lanuages, the "foreach" loop & "ZennoPoster.BulkMailDownload" need error/exception handling boilerplate to output to ZP log Class. At the moment, it looks like the code would swallow exceptions/errors.

ZennoLab.InterfacesLibrary.Enums.Email.EmailProtocol.POP3, 24*100, 5000, false);

In this code 24*100 Means 24 Hrs and 100 days.If message older than specified amount of hours will not be returned..

5000 Means BulkMailDownloader Download Max 5000 Messages from Mail Server..

False Means BulkMailDownloader will not delete Messages in Mail Server..

you can modify these settings in code what you want..!

i tested using this code working good..!!

I got the reason. When I save Tabl1 to a xls or xlsx file, it is always only 4 mails.

When I save Tabl1 to a txt file, it works ok.
