For sure, but everything is relative. Ignoring for a second the lock-in factor of using a @gmail.com address, I would trust Google's MX servers any day over Gandi's, especially after this last incident (trust == reliability in this context).

Google's MXes are notoriously strict and drop or permanently delay emails all the time for reasons beyond your control as a recipient an example from 5 minutes ago from one of my MX'es (which only forwards, after heavy greylisting and spam filtering): Jan 9 18:05:59 mail postfix/smtp[26197]: to=<ABC@gmail.com>, orig_to=<XYZ>, relay=alt1.gmail-smtp-in.l.google.com[209.85.233.26]:25, delay=25000, delays=25000/0.01/1.6/0.16, dsn=4.7.0, status=deferred (host alt1.gmail-smtp-in.l.google.com[209.85.233.26] said: 421-4.7.0 Our system has detected that this message is 421-4.7.0 suspicious due to the very low reputation of the sending domain.

  Interesting. Would you be of the opinion that sending mail from my personal @gmail.com address would then have much higher chances of being successfully delivered to other people (most of which will inevitably be at another @gmail.com address) than those sent from my "portable" @custom.domain address?

    if you're sending it inside the gmail interface to a gmail address I doubt it makes any difference sending to outside gmail I suspect it will count against you (though major providers likely have special treatment for Google's MXes)
