So, I help our my sister's business by handling her domain. For some
time she has paid for a virtual server with westhost.com, and on it, I
have a simple forward rule in /etc/aliases for her business account to
her gmail account, as she requested.
trish: tsoulier [ at ] gmail [ dot ] com
petservices: trish
So someone emailing petservices [ at ] pawsitiveapproach [ dot ] ca will result in a
forward to tsoulier [ at ] gmail [ dot ] com. This has been working fine.
Suddenly it's not.
----- The following addresses had permanent fatal errors -----
tsoulier [ at ] gmail [ dot ] com
(reason: 550-5.7.1 This message does not have authentication
information or fails to pass)
(expanded from: trish)
----- Transcript of session follows -----
... while talking to gmail-smtp-in.l.google.com.:
>>> DATA
<<< 550-5.7.1 This message does not have authentication information or
fails to pass
<<< 550-5.7.1 authentication checks. To best protect our users from
spam, the

<<< 550 5.7.1 information. s3si2560808iom.144 - gsmtp
554 5.0.0 Service unavailable
I don't understand why google is asking for authentication for a simple
forward. We're not relaying, we're forwarding.
I'm in the middle of moving her nameservers to use my config at
digitalocean so I can better control her setup, but I've had the same
issue there with a simple mail forward so I'm asking.
If I use postfix' virtual hosting, then that works. But why would a
simple /etc/aliases forward be rejected?
Help appreciated. Google's explanation is not helpful, at least to me.
Mike
