[Cialug] Gmail rejects

[Hasler, Chris]

It appears that Google may have recently made changes and they are now more finicky about authentication with 3rd party apps or scripts to GMails SMTP servers. 

Lots of report of problems and some fixes documented here:

Subject: [Cialug] Gmail rejects

Seeing a really weird problem with emails relayed via gmail:

<noc at omnitec.net> (expanded from <root>): host smtp.gmail.com[https://urldefense.proofpoint.com/v2/url?u=http-3A__74.125.69.108&d=BQICAg&c=GUDVeAVg1gjs_GJkmwL1m3gEzDND7NeJG5BIAX_2yRE&r=GXxd8Yye2eczAtdhphpq7XV3t9eWOHwaF519KS--Ch4&m=O9qVsHI4DUEoUxLvvcFkJS0RffO2Cj0SirSdYlWbJGo&s=zt-Rkv6ec9AgmdrAAaLewpoJGAte3gsYeFQdBjtFqDI&e= ]
    said: 553 5.1.2 The address specified is not a valid RFC-5321 address.
    g1sm460198ioe.5 - gsmtp (in reply to MAIL FROM command)

Sender log for a test message today:

Nov  3 23:21:16 Mainserver postfix/smtp[29935]: 1C5AD81716: to=<noc at omnitec.net>, orig_to=<root>, relay=smtp.gmail.com[https://urldefense.proofpoint.com/v2/url?u=http-3A__74.125.69.108&d=BQICAg&c=GUDVeAVg1gjs_GJkmwL1m3gEzDND7NeJG5BIAX_2yRE&r=GXxd8Yye2eczAtdhphpq7XV3t9eWOHwaF519KS--Ch4&m=O9qVsHI4DUEoUxLvvcFkJS0RffO2Cj0SirSdYlWbJGo&s=zt-Rkv6ec9AgmdrAAaLewpoJGAte3gsYeFQdBjtFqDI&e= ]:587, delay=0.85, delays=0.11/0.01/0.7/0.03, dsn=5.1.2, status=bounced (host smtp.gmail.com[https://urldefense.proofpoint.com/v2/url?u=http-3A__74.125.69.108&d=BQICAg&c=GUDVeAVg1gjs_GJkmwL1m3gEzDND7NeJG5BIAX_2yRE&r=GXxd8Yye2eczAtdhphpq7XV3t9eWOHwaF519KS--Ch4&m=O9qVsHI4DUEoUxLvvcFkJS0RffO2Cj0SirSdYlWbJGo&s=zt-Rkv6ec9AgmdrAAaLewpoJGAte3gsYeFQdBjtFqDI&e= ] said: 553 5.1.2 The address specified is not a valid RFC-5321 address. g1sm460198ioe.5 - gsmtp (in reply to MAIL FROM
command))

The interesting part is that on 2 November the cronjob emails are sent just fine (as shown in "Sent Mail" for that gmail account), .. on 3 November the SAME DAILY EMAIL is rejected.

Any thoughts on a possible cause, or just chalk it up to Google Madness?

	Thanks!
