Hello,
I have been using postfix on a local machine for a few years to act as a
relay for my domain to send email out through gmail.
This has worked well enough, but I noticed recently that I had some
email queued up and was not getting emails out any longer.
In my mailog, I am seeing these errors:
Jan 14 08:16:18 deathstar postfix/smtp[16142]: 8CBF11E12B5:
to=<michael@my.domain>, relay=smtp.gmail.com[173.194.203.108]:587,
delay=58297, delays=58297/0.05/0.71/0, dsn=4.7.0, status=deferred (SASL
authentication failed; cannot authenticate to server
smtp.gmail.com[173.194.203.108]: invalid parameter supplied)
I have googled a lot, but I am not finding anything that matches this
error message. I am not sure also what might have changed to cause
this. Not sure if Google changed something or a package update broke
something, etc.
This is in Fedora 29, x86_64, postfix-3.3.1, and
cyrus-sasl-lib-2.1.27-0.3rc7.
