Not what it seems to me at least. The number of times I've seen this problem not just here but from other forums as well made me unable to merely call it "sometimes".
How many times did this problem occur for your account in this month, and what webmail service are you using?
That said, if its not "sometimes", then its "always". Then can it can happen to anyone for more than 50 times in one month?
Last time I check, common doesn't equate always. It is defined here as "a more likely occurence" while "always" means at all times. Clearly, I wasn't saying that this problem happens everytime a user logs in.
And I didn't arrived on the said conclusion because I was thinking of the number of times it could occur in single person (+time). I was thinking of it as a whole; how most users are likely to have experienced this problem at least once.
Ok. But would the problem also be from the side of the email provider? I think some of the incoming mail servers of those less popular webmails are blocking some emails from services that might be mistaken for spam.
What was the email provider used by neur0?
