Hi All, I've heard that sendmail can be configured to do store-and-forward of email for people/orgs who have a mail server without a full time internet connection. example: company with a mail server in-house and a dialup ISDN line. I know POP3 could be used in a situation like this but alot of folks are asking for store-and-forward these days. Is this right? Does anyone know where to start? A search of the FreeBSD mailing list archives turned a blank. here's part of a document I have explaining the technology: ================================================================ Store. Your ISP's mail server must be configured to store your mail for you. Default Sendmail behaviour is to attempt resends with specific intervals and eventually give up unless it happened to try to send while your connection was up. This will obviously not work reliably in a dial-up environment. Since Sendmail can be painful to set up in the first place, many providers give up at the prospect of setting it to store mail. Infact, there are versions of Sendmail that simply can not be configured for this but instead need to be re-written. Forward. Your ISP's mail server (FingerHost) must be configured to listen to the finger port (79) for a specific commandstring (FingerCommand). This would be your mail server's way of alerting the ISP to make it send stored mail in to your local SMTP server. Both the FingerHost and FingerCommand should be provided by your Internet provider. It is fairly common practice to use the mailhost (MailServerIP) as FingerHost and your Internet domain name (acme.com) as FingerCommand, but it is entirely up to your provider. Also, your provider might give you the finger information on the format fingercommand@fingerhost. ================================================================ ..any help or direction would be greatly appreciated! -- sincerely, Dave ************************************************************ David A Richards Systems Integrator The illumen Group, Inc. http://www.illumen.com Email mailto:dar@illumen.com Personal Web http://www.illumen.com/~dar ************************************************************
