[Cialug] Gmail rejects

[L. V. Lammert]

Seeing a really weird problem with emails relayed via gmail:

<noc at omnitec.net> (expanded from <root>): host smtp.gmail.com[74.125.69.108]
    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[74.125.69.108]:587, delay=0.85, delays=0.11/0.01/0.7/0.03, dsn=5.1.2, status=bounced (host
smtp.gmail.com[74.125.69.108] 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!
