Disappearing mail

R9. Fetchmail fails when used with a dynamic PPP link.

+ +The diagnostic of this problem is that your MTA, on the receiving end +of an SMTP forward from fetchmail, refuses a RCPT TO delivery address +with the complaint 551 ... we do not relay.

+ +In order to avoid giving indigestion to certain picky MTAs (notably exim), fetchmail always makes the RCPT TO address it +feeds the MTA a fully qualified one with a hostname part. Normally it +does this by appending @ and your client machine's hostname.

+ +This, however, can creates problems when your MTA is running in daemon +mode and outlasts the dynamic IP address assignment your client +machine had when the MTA started up. Since the new IP address (looked +up at RCPT TO interpretation time) doesn't match the original, your +MTA thinks it's seeing a relaying attempt and refuses.

+ +The simplest way to fix this is to use the smtpaddress +option to force the appended hostname to one with a (fixed) IP address +of 127.0.0.1 in your /etc/hosts. (The name `localhost' +will usually work).

+ +If your MTA is sendmail, another fix is to restart each time you connect +to your ISP:

+ +

+        kill -HUP `head -1 /var/run/sendmail.pid`
+
+ +If this doesn't fix it, you might have to put your dynamic IP address +in whatever your sendmail is using for a cw file (/etc/sendmail.cw). +Ryan Murray reports "my ip-up script for PPP puts my fully qualified +domain name at the bottom of /etc/hosts (building from a template), +sends the name off to sendmail.cw, restarts sendmail, and then starts +fetchmail."

D1. I think I've set up fetchmail correctly, but I'm not getting any mail.
