Hello. With FC2 I thought I'd have a go at hosting my own mail for the first time. Sendmail, procmail, and Dovecot are all working fine, but hotmail and yahoogroups seem to be refusing to accept mail from me. I use a fat mail client (thunderbird) when I'm at home and a web based one (horde imp) when I'm away. Thunderbird sends mail using my ISP's smtp server, so from there I can send mail to hotmail and yahoogroups just fine. When I'm away using the web based client, it uses sendmail directly, and the mail sits in /var/spool/mqueue for five days until it bounces. 'mailq' shows: /var/spool/mqueue (1 request) -----Q-ID----- --Size-- -----Q-Time----- ------------Sender/Recipient-----------i5S8v2K3018352 2893 Mon Jun 28 09:57 <my@xxxxxxxxxxx> (reply: read error from mx1.hotmail.com.) <addressee@xxxxxxxxxxx> Total requests: 1 What I want to know is this: what do I have to do to sendmail.mc to get sendmail to do as thunderbird is doing and just talk smtp to my ISP's smtp server for remote delivery, but carry on doing what its doing now for local delivery? Cheers, Eliot.
