(Chilkat2-Python) Imap.GetMailSize vs Email.SizeShows how to get the total size of an email, as well as the sizes of the attachments. This can be done when either full-emails or headers-only are downloaded. Note: This example requires Chilkat v11.0.0 or greater.
import sys import chilkat2 success = False # This example assumes the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. imap = chilkat2.Imap() # Connect to an IMAP server. # Use TLS imap.Ssl = True imap.Port = 993 success = imap.Connect("imap.someMailServer.com") if (success == False): print(imap.LastErrorText) sys.exit() # Login success = imap.Login("****","****") if (success == False): print(imap.LastErrorText) sys.exit() # Select an IMAP mailbox success = imap.SelectMailbox("Inbox") if (success == False): print(imap.LastErrorText) sys.exit() # Get the message IDs of all the emails in the mailbox # We can choose to fetch UIDs or sequence numbers. fetchUids = True messageSet = chilkat2.MessageSet() success = imap.QueryMbx("ALL",fetchUids,messageSet) if (success == False): print(imap.LastErrorText) sys.exit() # When downloading headers, each email object contains # (obviously) the headers, but the body will be missing. # Attachments will not be included. However, it is # possible to get information about the attachments # as well as the complete size of the email. bundle = chilkat2.EmailBundle() headersOnly = True success = imap.FetchMsgSet(headersOnly,messageSet,bundle) if (success == False): print(imap.LastErrorText) sys.exit() # Loop over the email objects and display information about each: email = chilkat2.Email() i = 0 j = 0 numEmails = bundle.MessageCount while i < numEmails : bundle.EmailAt(i,email) # Display the From and Subject print(email.From) print(email.Subject) # Display the recipients: j = 0 while j < email.NumTo : print("TO: " + email.GetToName(j) + ", " + email.GetToAddr(j)) j = j + 1 j = 0 while j < email.NumCC : print("CC: " + email.GetCcName(j) + ", " + email.GetCcAddr(j)) j = j + 1 # Show the total size of the email, including body and attachments: print(str(email.Size)) # When a full email is downloaded, we would use the # email.NumAttachments property in conjunction with the # email.GetMailAttach* methods. # However, when an email object contains only the header, # we need to access the attachment info differently: numAttach = imap.GetMailNumAttach(email) j = 0 while j < numAttach : print(imap.GetMailAttachFilename(email,j)) attachSize = imap.GetMailAttachSize(email,j) print(" size = " + str(attachSize) + " bytes") j = j + 1 print("--") i = i + 1 # Disconnect from the IMAP server. success = imap.Disconnect() |
