You configure how VPOP3 is to send outgoing mail on the Out Mail settings page. Each Out Mail method is associated with a Connection method. So, to create a new Out Mail method you need to create a new Connection method (External Mail -> Connection -> New)- the Add Connection wizard will also take you through adding the associated Out Mail method.
You can define Outward Mail settings for each VPOP3 Connection. This is to allow sending of mail whichever Connection VPOP3 uses. Many ISPs are now implementing ‘anti-relay’ measures to prevent their mail servers being used by SPAMMERS. The effect of this is that you can only use their SMTP servers if you are accessing the Internet through a connection to their access servers.
You may also run other in-house mail servers at other sites. Using this method you can send certain mail to those servers whilst sending generic Internet mail to the ISP. (See also LAN Forwarding).
There are three different types of Out Mail type:
1. Via SMTP Relay
This is usually the best way for sending outgoing mail if you are connected to an ISP via a dial-up/ISDN/xDSL connection. You specify the name of your ISP's SMTP server as a relay server. All outgoing mail is sent to that server which then will send it to the target recipients.
This is usually the best way if you are connected to the Internet using a leased line connection. Often more data needs to be sent if you use this method so it is can be slower than the previous method, but some ISPs don't allow the use of their relay servers if you have a leased line connection. Note that if you have been assigned a dynamic IP address by your ISP some domains (eg AOL, Yahoo etc) will not allow you to send mail directly to them - use the SMTP Relay method instead.
This is used when two VPOP3 servers need to communicate over a link which doesn't support TCP/IP protocols like SMTP - The Windows 95 dial-in server doesn't support TCP/IP, so if you are using that as a dial-in server you will probably need to use this method. This option is rarely needed.
The details below are for SMTP Relay, click here for SMTP Direct or here for VPOP3 File Transfer settings.
The Only send messages waiting at start of connection option tells VPOP3 not to send any messages which arrive in the OutQueue once the outgoing connection has started.
The Send smaller messages first option tells VPOP3 to sort the outgoing messages into size order and send the smaller messages first, followed by the larger messages.
In the SMTP Relay Servers box, enter zero or more SMTP servers which can be accessed using this Connection (if there is more than one server, each one should be entered on its own line). VPOP3 will go through this list of servers until it find one which responds, and then it will use that server to send all the valid outgoing mail. If the list is empty, or it cannot find a responding server, then VPOP3 will simply not try to send any outgoing mail.
If the SMTP server is not on TCP/IP Port 25, then enter then server name in a format similar to: mail.isp.com:1025.
The Domain Filtering section lets you define which messages can be sent out through this SMTP relay server.
There are two options, you can define which domains can be sent To, and you can define which addresses can be sent From
The syntax of the Domain Filtering entry is that you enter a list of:
- email domains which VPOP3 can send to (just as the email domain name - eg microsoft.com - do not enter a full email address or @ character)
- email domains which VPOP3 can not send to (as the email domain prefixed by a ! - eg !ibm.com - do not enter a full email address or @ character)
- email addresses which VPOP3 can send from (as the email address prefixed by a From: - eg From: *@pscs.co.uk)
- email addresses which VPOP3 can not send from (as the email address prefixed by a !From: - eg !From: colin@pscs.co.uk)
If you do not have any email domains filtering the To address, then VPOP3 will allow sending to any address, but if you have any To filters, VPOP3 will not allow sending to any other addresses
If you do not have any email addresses filtering the From address, then VPOP3 will allow sending from any address. If you have any allowed From addresses, VPOP3 will disallow messages from any other addresses, if you have only disallowed From addresses, VPOP3 will allow messages from any other address.
Note that you can use wildcards to specify the To domains, or From addresses.
The Max Recipients Per message setting tells VPOP3 the maximum number of recipients which the ISP will accept for each outgoing message, so that VPOP3 can split up the message accordingly. Some ISPs have a limit to try to reduce the use of their servers for junk-emailing. Unfortunately this can also make it difficult to run legitimate mailing lists through those ISPs. This setting allows VPOP3 to send mailing list messages through ISPs with a per-message recipient limit. You may have to discover the best value for this setting by trial and error because many ISPs don't make this server restriction publicly known.
If your ISP requires you to log on to their SMTP server, enter the relevant details in the SMTP Authentication section. Some ISPs use an alternative form of authentication called 'POP3 before SMTP authentication'. You can tell VPOP3 to use that on the Utilities -> Misc Settings page.
The SMTP Return Address Modifiers section lets you set basic rules to make VPOP3 change the email 'return address' (the address that bounce messages go to) because some ISPs will reject messages that aren't from a return address that they have told you to use. See here for more details.
