You can configure YPOPs! by right-clicking on the YPOPs! icon in the system tray and selecting Configure.
The following options can be configured:
Empty Trash on exit: Enable this if you want YPOPs! to clear your trash folder when it has finished downloading your emails.
Empty Bulk Mail on exit: Enable this if you want YPOPs! to clear your bulk mail folder when it has finished downloading your emails. You can choose not to download emails from your bulk mail folder, and this option will come in handy to clear the folder without you having to go and clear it up yourself.
Mark Messages as Unread on Yahoo Mail server: Enable this if you want YPOPs! to mark messages as unread on Yahoo. This only works if the e-mail client is configured to leave the message on server.
Maximum number of emails per pass: This option is very important and must be configured with an ideal value for your type of usage. If you receive too many emails or emails with large attachments, then the value of this field should be kept to a low number to ensure that the emails are downloaded to your mail client without it timing out. The remaining emails can be downloaded with another Check email operation from your client. Also, ensure that you have enabled the Delete messages from mail server in your mail client.
Apply limit to message list: Enable this if you want YPOPs! to apply the Maximum number of emails per pass limit to the message list. This has the affect of hiding any additional emails in the folders from the email client – as if there is nothing else there. One reason NOT to do this is that if you tell your email client not to delete emails from server (possibly until later), then the email client will think those emails are not on the server any more. This can have undesirable side affects, such as duplicate emails, emails not being removed from Yahoo, etc. If deleting emails during download, this option is useful to avoid the email client from displaying an ugly error when the limit is reached (when there are more new emails than allowed to download in a single pass). This is also useful for DSL users, because DSL can do things a little fast and Yahoo may give error 999 which will lock the user out of their Yahoo account for an hour.
Download Email Category: Yahoo categories emails as follows: Unread messages, flagged messages and all messages. You can select the type of emails that you want to download.
Yahoo Mail allows user defined folders to be created and filters defined to automatically filter emails into these folders. If you want to download emails from such user-defined folders, you can specify the names of the folders here.
System Folders:
Inbox: Enabling this allows YPOPs! to analyze and download any emails in your Inbox folder
Bulk Mail: Enabling this allows YPOPs! to analyze and download any emails in your Bulk Mail folder. Bulk Mail folders in all probability will have junk emails/spam and you can disable this if you do not want to download any emails from this folder.
YPOPs! support a limited amount of SMTP functionality that can be used to send emails from your mail client. If you would like to save a copy of each email that has been sent via your Yahoo account, in Yahoo's Sent Items folder, enable the option.
Keep Session alive for ___ seconds: YPOPs! keeps the Yahoo! Mail session alive for the number of seconds you specify. If you specify 0 (zero), YPOPs! will end the session after completing a POP3 pass checking for new email or an SMTP pass of sending emails. This was previously known as Cookie Timeout.
Connect via HTTP proxy: This option would be used mostly in corporate networks which use proxy servers. Check this box if you connect to the Internet via a web proxy server. Once checked, the HTTP proxy and HTTPS proxy text fields get enabled. Enter the appropriate details.
Proxy Authentication: If your proxy server requires proxy authentication, then you can enter your username and password by enabling proxy authentication. Please note that YPOPs! supports Basic Authentication only. Support for Digest Authentication and NTLM has not been provided.
Bind on I.P address: If your PC is on a network (LAN, Cable, etc) it might have an I.P assigned to it. You can specify the I.P address YPOPs! should bind on here. By default, it will use localhost, i.e., 127.0.0.1. By specifying a "non- localhost" I.P, users in the network can access YPOPs! running on your PC. Any changes made to the I.P here, requires YPOPs! to be restarted for the change to take affect.
NOTE: The help assumes that localhost is the I.P which will be used by YPOPs! If you use some other I.P address, please keep that in mind when reading the rest of the help file.
POP3 Port: POP3 mail servers run on port 110 by default. This is the default port number for YPOPs! as well. But, if you already running a mail server or have an antivirus application with email scanning enabled, then in all likelihood you have not been able to run YPOPs. You can either change the port settings in your mail server or change it in YPOPs. YPOPs can run on any TCP port in the range 1 - 65535. Change the port number here, and make the necessary change in your account settings in your email application as well. Restart YPOPs! for this change to take affect.
Enable SMTP: Enable this option if you would like to use the SMTP feature of YPOPs!. Make a note that the SMTP feature in YPOPs! is currently experimental and even when fully implemented, will not be able to support the same level of features one finds in standard SMTP servers. This is because the SMTP feature in YPOPs! is emulated and can support what Yahoo Mail's Compose Email feature provides.
SMTP Port: If the SMTP feature has been enabled, this option will be active. SMTP servers run on port 25 by default. You might get errors that this port is already in use. This could be because of the presence of other mail servers, or anti-virus programs on your PC. You can change the port accordingly to avoid this error.
Create an activity log: Enable this if you want a log file to be created. This is useful for debugging problems being faced in configuring YPOPs!
Logging Level: Advanced logs dump more data into the log file compared to the basic log.
Limit the size of the log: The maximum size the log file can grow to. Once the size is reached, the log file is deleted.
User Agent: The default user agent will be fine in practically 100% of the scenarios. There should be no need to change the value of this field. This option is provided to fool Yahoo! into believing that a well-known (or not-so-well-known if you prefer) web browser is connecting to its web site. You can enter your own value if you don’t like any of the values in the pull-down list.
Download emails silently: If you do not want any popup windows showing the progress of the message download, then you can enable this feature. This is ideal if you want YPOPs to check for your email in the background without you being disturbed.
Automatically start YPOPs! when Windows starts: Enable this if you would like YPOPs! to be launched when Windows is started. Enabling this option creates a shortcut for YPOPs! in the Windows Startup folder.
Status window always on top: Enable this option if you would like to have the email download/send window always on top of other windows.
Hide tray icon: Enable this option if you would want to hide the system tray icon. One reason to do this is if you wish to make YPOPs! a service that doesn’t interact with the desktop (which it can’t do before you are logged in).
Enable UIDL (unique msg id) support (recommended): Enable this option if you would like to enable support for unique message ids between YPOPs! and your email client. This allows your email client to uniquely identify each message and avoids mistaking one message for another between sessions.
