Why? Mail-in voting is hardly unique to the US; what made you suspicious?
So when a global pandemic occurs and we're trying everything we can to isolate and socially distance, that priority changes real quick. People get talking and problems get solved.
Of course, sore losers will complain about anything to justify their loss, and this "new thing" was a prime scapegoat. It was also well known ahead of time that the mail in votes would be largely Democratic (because COVID was VERY politicized and democrats were more likely to follow quarantine guidance and therefore vote by mail). So when the votes came in, they pointed to that imbalance and called it "fraud".
Besides all that, there's no reason to be more suspicious of mail-in ballots than in-person ones. In-person, you mark a paper ballot and then put it in a stack... which then gets mailed somewhere else. If someone is going to be changing mail-in ballots, then they're already in a position to be changing regular ones as well (and every election security professional will tell you that paper ballots are more secure than electronic ones).
The one advantage of physical voting I can think of is the ability to just be close to voting station on voting day, counting people who go in there, asking people (who are willing to share) for whom did they vote. This allows to independently check if fraud exists.
(A few people have been charged with voting their spouse's ballots.)
Unfortunately in 2020 the fringe became the GOP mainstream, treating equally soft claims as fact.
"Seventy-two percent (72%) of Democrats believe it’s likely the 2016 election outcome was changed by Russian interference, but that opinion is shared by only 30% of Republicans and 39% of voters not affiliated with either major party."

Russia absolutely did and continues to push propaganda into elections in the USA and elsewhere. That's not really in dispute at this point so I'm not surprised it polls that high.
Got a poll that shows similar numbers for fraud? I would be genuinely surprised to see that.
I should actually note here that I didn't vote for Trump, either time, nor did I vote for Clinton or Biden.
I just hate hypocrisy.
That sounds like a perfectly reasonable claim with evidence that supports it, paralleled by other elections in other countries as well; quite obviously very different to what was discussed above.

In 2020, Hillary Clinton was still casting aspersions regarding the outcome of the 2016 election, sowing discontent about the electoral college, preparing Democrat voters to ignore the results until Joe Biden was declared the winner.
Portraying this game as if it's only being played by one team does not help restore any trust in the federal election process.
But she doesn't count as "anyone", I guess?
In other words: not saying that there was actual fraud sufficient to change the election, not saying the election was "stolen" in the sense people seem to be saying here.
Stolen by foreign influence is very different than what the 2020 nuts have claimed. How many court cases did they lose? How many times were they asked to produce evidence and came up with ... nothing?
The bigger problem in that election was Russian-intelligence-stolen (and possibly tampered with) documents being released to the press in the lead up to the election in coordination with the Trump campaign (with the FBI keeping its investigation of that secret), and then the FBI director making an unprecedented and (we found out only afterward) unsupportable statement attacking Clinton immediately before the election, after being pressured into it by a handful rogue FBI agents who were friends of Trump’s campaign threatening insubordination.
And perhaps the biggest problem of all, an entirely too credulous mainstream media who didn’t put those developments in context, leaving voters to draw mistaken inferences, and giving oodles of free airtime to Trump’s rallies without making any effort to dispute outright lying in real time.
