My reply seems not to have been posted, so to restate: I have an ADSL dialup with AOL, and sendmail fails. > Mar 6 22:11:34 base sendmail[13523]: j26KMbkD012891: > to=<w.murray@xxxxxxxx>, ctladdr=<root@MY-HOME-DOMAIN> (0/0), > delay=01:48:53, xdelay=00:00:00, mailer=relay, pri=802987, > relay=XXXXXX.rl.ac.uk., dsn=4.0.0, stat=Deferred: Name server: > XXXXXX.rl.ac.uk.: host name lookup failure > > Thanks for the help. I've followed a couple of suggestions: *) Forget ssl, use my ISP's SMTP server. This is smtp.aol.com The result is identical, with my work IP changed to smtp.aol.com At least it proves ssl wasn't the problem! *) Try "MASQUERADE_DOMAIN" I try many combinations, (aol.com), (ipt.aol.com), and I get one of: dsn=5.6.0, stat=Data format error or dsn=4.0.0, stat=Deferred: Name server: smtp.aol.com: host name lookup failure I guess the 5.6.0 might be progress? But 'data format error' doesnt' give many clues as to where this has been encountered. Also, ctladdr stays fixed as root@MYDOMAIN-COM, throughout. Should it change? Running sendmail on the command line has it still picking up the name 'after readcf'. I tried ading by hand Djaol.com in sendmail.cf but it didn't change anything. Does anyone have any more clues how I can override the name? I suppose I could somehow change the name after dial-up, but as this is a NAT routing point it doesn't seem to make sense internally.
