Hi, how do I tell if a message is deleted, waiting to be purged?
I'm running a process that goes through a mailbox to log certain emails to a database and then deletes them, but if the process breaks for any reason, the expunge might not happen and the message will be still be picked up again despite being flagged for deletion on the next run so I'd like to check the email's delete status as I go along.
Wouldn't matter too much but there's a lot of emails come in, last run was about 136000 messages (several months worth, and the expunge took so long it timed out and raised an exception! While I'm at it, is there a way to increase the timeout?
Many thanks, hope you can help
Cheers

Hi, I know I could call the expunge method after each delete, but given the size of the mailbox, it slows down processing a lot...

You should increase Imap.Timeout value (20000 milliseconds is default).

Maybe, you may call Expunge twice? First time, when you select the folder (prior to processing any messages), and second time after you finished processing messages.
Code:
imap.SelectFolder(folder);
imap.Expunge();
// Main processing
imap.Close();
|

Note using Close instead of Expunge in the end. On some servers, Close may be faster (well, hell faster) than Expunge. This is because the server knows the client left this folder and does not want to wait until expunge completes (and thus expunge may run in the background).
Regards,
Alex

Hi thanks for that, can I tell if a message has a status of 'deleted' though? I'd like to make the system aware of deleted messages so that I can ignore them if they are there!
Thanks
Martin

When your application downloaded envelopes, it may check "Deleted" flag of each envelope to know if the message is marked for removal.
Best regards,
Andrew

That's great, worked a treat!
I just downloaded the envelope collection for a single message UID, and checked for 'Deleted' in the flags.ToString of the envelope at index zero in the collection...
Thanks Again
Martin
