 |
|
I have the following in /etc/postfix/main.cf
| Code: | myhostname = mail.tomek.ca
mydestination =
$myhostname,
localhost.$mydomain,
eigen.$mydomain,
$mydomain,
localhost
alias_maps = hash:/etc/mail/aliases
alias_database = hash:/etc/mail/aliases
mail_spool_directory = /var/spool/mail/
local_destination_concurrency_limit = 1
message_size_limit = 0
masquerade_domains = $mydomain
masquerade_exceptions = root
relay_domains = |
For some reason, if I change the myhostname variable to mail.tomek.ca, where the real computer name is eigen.tomek.ca, sending mail fails. It doesn"t bounce, just doesn't appear anywhere.
For example, here's the output of /var/log/mail.info when I send an email from user tom to tomek32@gmail.com
| Code: | Sep 4 23:19:25 eigen postfix/pickup[22645]: 1937913AAC: uid=1000 from=<tom>
Sep 4 23:19:25 eigen postfix/cleanup[22841]: 1937913AAC: message-id=<20040905031924.GA22833@eigen>
Sep 4 23:19:25 eigen postfix/qmgr[22646]: 1937913AAC: from=<tom@tomek.ca>, size=376, nrcpt=1 (queue active)
Sep 4 23:19:25 eigen postfix/smtp[22843]: 1937913AAC: to=<tomek32@gmail.com>, relay=none, delay=0, status=deferred (Host or domain name not found. Name service erro
r for name=gmail.com type=MX: Host not found, try again) |
but if I change i comment out the myhostname variable, sending mail works, and here's what I get in the logs
| Code: | Sep 4 23:22:36 eigen postfix/pickup[22982]: 07D7D13A7E: uid=1000 from=<tom>
Sep 4 23:22:36 eigen postfix/cleanup[22997]: 07D7D13A7E: message-id=<20040905032235.GA23013@eigen>
Sep 4 23:22:36 eigen postfix/qmgr[22983]: 07D7D13A7E: from=<tom@tomek.ca>, size=377, nrcpt=1 (queue active)
Sep 4 23:22:36 eigen postfix/smtp[22986]: 07D7D13A7E: to=<tomek32@gmail.com>, relay=gsmtp171.google.com[64.233.171.27], delay=0, status=sent (250 OK 1094354547)

Why would changing myhostname to a different name from the actual computer name cause postfix to not be able to resolve gmail.com?
Don't know if it matters, I run a dns server aswell, where the MX record points to mail.tomek.ca |
