I can't send email from my server to gmail addresses
I have a VPS server that I host some domains on for myself and clients. A client wants a catch-all on a domain that gets forwarded to an existing Gmail account.
"Simple", I say and go through a quick tutorial on it. For testing I forward
email@example.com (of course these aren't real - but the proper values are correct).
Now to test it. First I wrote an email to
firstname.lastname@example.org using Mutt on the server. Two seconds later an email plops into my
email@example.com inbox (which is actually a Gmail for domains account).
But for a real test I sent an email from
firstname.lastname@example.org, expecting to just email myself. Nothing came through. I can't find anything in spam or imagine any way that a filter could have caught it. I've looked everywhere for it.
I then decided to check on the server. In /var/log/mail.log there is a beautiful section:
Oct 3 12:59:40 nj postfix/qmgr: 9AFE448161: from=<email@example.com>, size=1063, nrcpt=1 (queue active) Oct 3 12:59:41 nj postfix/smtp: 9AFE448161: to=<firstname.lastname@example.org>, orig_to=<email@example.com>, relay=ASPMX.L.GOOGLE.com[188.8.131.52]:25, delay=1.1, delays=0.29/0.01/0. 11/0.67, dsn=2.0.0, status=sent (250 2.0.0 OK 1317642647 et3si10294675wbb.52) Oct 3 12:59:41 nj postfix/qmgr: 9AFE448161: removed Oct 3 13:00:10 nj postfix/smtpd: disconnect from mail-yx0-f177.google.com[184.108.40.206]
That looks good. I've had a look at the part where Mutt sent its message, and it's like-for-like.
Because it's connecting, that suggests the firewall is okay (and I explicitly allow p25).
Is the email getting rejected by Google? Wouldn't it change the status of the send message (above) to something other than OK? What can I test next?
